Hi, yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet. I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org Guillaume On Mon, Jan 18, 2010 at 10:05 AM, Petteri Karttunen < [email protected]> wrote:

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Hi guys, getting some informations since i can't find just at looking at the code how this would append. When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ? And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext())

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Hello,

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin  10095     tomcat  666r      REG      104,1  60931511   15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin  10095     tomcat  667r      REG      104,1  60931507   15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin  10095     tomcat  668r      REG      104,1  60931507   15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext())

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Hi Gerritjan,

Can you paste in more information about the error?

For your informations: as far as i can see in the code there is only one way to have the IndexUpdater to null (whichgenerate a nullpointerexcetion in #getQueueSize) is when during the init the index can't be opened. In this case you should find a log looking like this: "Failed to open the index directory: " followed with a message detailing a little why it can't open index directory. (so indeed it could be caused by the fact that no more inode can be used on linux for example). Could you look if you can find this error anywhere in the log ?

Hello,

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin  10095     tomcat  666r      REG      104,1  60931511   15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin  10095     tomcat  667r      REG      104,1  60931507   15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin  10095     tomcat  668r      REG      104,1  60931507   15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Navigating to the Main.LuceneSearch page brings up the following error?

Can you paste in more information about the error?

Everything I could find was this one problem in closing the writer:

23:00:06,242 [Lucene index updating thread] [Lucene Index Updater] WARN  lucene.IndexUpdater             - Failed to close writer.

I forgot to mention another symptom suggesting index reading problems: when the situation is on I can do Lucene-queries (custom search page wo getQueueSize()) but it just doesn't return anything. So the plugin kind of "works" but "seems" not to be able to read indexes properly.

As far as i can see in the code all search* methods in the public api are "protected" from any Exception and return null when something wrong happen. But it also log the error so when you do a failing search you should have something in the log.

For your informations: as far as i can see in the code there is only one way to have the IndexUpdater to null (whichgenerate a nullpointerexcetion in #getQueueSize) is when during the init the index can't be opened. In this case you should find a log looking like this:

"Failed to open the index directory: " followed with a message detailing a little why it can't open index directory.

(so indeed it could be caused by the fact that no more inode can be used on linux for example).

Could you look if you can find this error anywhere in the log ?

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin  10095     tomcat  666r      REG      104,1  60931511   15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin  10095     tomcat  667r      REG      104,1  60931507   15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin  10095     tomcat  668r      REG      104,1  60931507   15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext())

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

I wish there was more info in my logs...I paused actively watching and debugging this one few weeks ago because of the workaround (reinitializing the plugin when needed in a groovy try{...getQueueSize()...} catch -block on a search page). As far as I can remember there wasn't any lucene-errors in my logs at the time and the search clearly returned 0 hits according to logs. To be sure I'll put the debugging options on again and let you know the results as soon as the problem occurs again. Are these enough?: log4j.logger.com.xpn.xwiki.plugin.lucene.IndexData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.DocumentData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexUpdater=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexRebuilder=debug log4j.logger.com.xpn.xwiki.plugin.lucene.LucenePlugin=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResults=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResult=debug I haven't examined the code thoroughly so probably a missed shot but is there any chance that this could be a method synchronization issue with searchers and writers? -Pete -----Alkuperäinen viesti----- Lähettäjä: [email protected] [mailto:[email protected]] Puolesta Thomas Mortagne Lähetetty: 20. tammikuuta 2010 17:14 Vastaanottaja: XWiki Users Aihe: Re: [xwiki-users] Lucene defaultpage fails On Wed, Jan 20, 2010 at 16:01, Petteri Karttunen <[email protected]> wrote:

Everything I could find was this one problem in closing the writer:

23:00:06,242 [Lucene index updating thread] [Lucene Index Updater] WARN lucene.IndexUpdater - Failed to close writer.

I forgot to mention another symptom suggesting index reading problems: when the situation is on I can do Lucene-queries (custom search page wo getQueueSize()) but it just doesn't return anything. So the plugin kind of "works" but "seems" not to be able to read indexes properly.

As far as i can see in the code all search* methods in the public api are "protected" from any Exception and return null when something wrong happen. But it also log the error so when you do a failing search you should have something in the log.

For your informations: as far as i can see in the code there is only one way to have the IndexUpdater to null (whichgenerate a nullpointerexcetion in #getQueueSize) is when during the init the index can't be opened. In this case you should find a log looking like this:

"Failed to open the index directory: " followed with a message detailing a little why it can't open index directory.

(so indeed it could be caused by the fact that no more inode can be used on linux for example).

Could you look if you can find this error anywhere in the log ?

Hello,

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin 10095 tomcat 666r REG 104,1 60931511 15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin 10095 tomcat 667r REG 104,1 60931507 15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin 10095 tomcat 668r REG 104,1 60931507 15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext())

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Hello, I've been running xwiki with "log4j.logger.com.xpn.xwiki.plugin.lucene=debug" now for some days. The problem has occurred several times but I've nothing in my logs. Is there something else I could do/debug? -Pete -----Alkuperäinen viesti----- Lähettäjä: [email protected] [mailto:[email protected]] Puolesta Thomas Mortagne Lähetetty: 20. tammikuuta 2010 19:28 Vastaanottaja: XWiki Users Aihe: Re: [xwiki-users] Lucene defaultpage fails On Wed, Jan 20, 2010 at 17:12, Petteri Karttunen <[email protected]> wrote:

I wish there was more info in my logs...I paused actively watching and debugging this one few weeks ago because of the workaround (reinitializing the plugin when needed in a groovy try{...getQueueSize()...} catch -block on a search page). As far as I can remember there wasn't any lucene-errors in my logs at the time and the search clearly returned 0 hits according to logs. To be sure I'll put the debugging options on again and let you know the results as soon as the problem occurs again. Are these enough?:

log4j.logger.com.xpn.xwiki.plugin.lucene.IndexData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.DocumentData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexUpdater=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexRebuilder=debug log4j.logger.com.xpn.xwiki.plugin.lucene.LucenePlugin=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResults=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResult=debug

You can use log4j.logger.com.xpn.xwiki.plugin.lucene=debug I think but AFAIK there is almost no debug log in Lucene plugin.

I haven't examined the code thoroughly so probably a missed shot but is there any chance that this could be a method synchronization issue with searchers and writers? -Pete

Everything I could find was this one problem in closing the writer:

23:00:06,242 [Lucene index updating thread] [Lucene Index Updater] WARN lucene.IndexUpdater - Failed to close writer.

I forgot to mention another symptom suggesting index reading problems: when the situation is on I can do Lucene-queries (custom search page wo getQueueSize()) but it just doesn't return anything. So the plugin kind of "works" but "seems" not to be able to read indexes properly.

As far as i can see in the code all search* methods in the public api are "protected" from any Exception and return null when something wrong happen. But it also log the error so when you do a failing search you should have something in the log.

For your informations: as far as i can see in the code there is only one way to have the IndexUpdater to null (whichgenerate a nullpointerexcetion in #getQueueSize) is when during the init the index can't be opened. In this case you should find a log looking like this:

"Failed to open the index directory: " followed with a message detailing a little why it can't open index directory.

(so indeed it could be caused by the fact that no more inode can be used on linux for example).

Could you look if you can find this error anywhere in the log ?

Hello,

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin 10095 tomcat 666r REG 104,1 60931511 15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin 10095 tomcat 667r REG 104,1 60931507 15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin 10095 tomcat 668r REG 104,1 60931507 15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

...

Also, xwiki gets the plugin object normally during the malfunctional state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?

The following command (thanks Pete) worked en reinitialized Lucene after that lucenesearch worked again.

Hope to hear soon how to prevent that Lucene is not initialized?

Hi,

yes, I'm frequently hitting this error too and I'm not sure why. Thomas Mortagne looked at it last week but he doesn't have a fix yet.

I was provided with a workaround last friday, I'll see if I can post it on code.xwiki.org

Hi,

I'm also encountering this problem randomly since XWiki 2.0 but so far haven't been able to find the initial cause. See also http://www.mail-archive.com/[email protected]/msg09549.html. As Marius suggests it might have something to do with the plugin initialization because re-initializing the plugin under those circumstances helps in my case:

...

xwiki.getXWiki().getPluginManager().getPlugin("lucene").init(xwiki.getXWikiC ontext()) ...

but this of course doesn't solve the problem behind.

Hello, I've been running xwiki with "log4j.logger.com.xpn.xwiki.plugin.lucene=debug" now for some days. The problem has occurred several times but I've nothing in my logs. Is there something else I could do/debug?

As i said i doubt "log4j.logger.com.xpn.xwiki.plugin.lucene=debug" bring anything since Lucene plugin does not print any debug log (or almost nothing and not useful here).

Only part of the code i see where it's possible to have the variable null (which makes it produce a nullpointerexception) are supposed to be covered by an error log at some point (not when you look at the page but before). I can't see how you could have this issue if nothing goes wrong and is then logged.

Not that this issue as finally been fixed !

I wish there was more info in my logs...I paused actively watching and debugging this one few weeks ago because of the workaround (reinitializing the plugin when needed in a groovy try{...getQueueSize()...} catch -block on a search page). As far as I can remember there wasn't any lucene-errors in my logs at the time and the search clearly returned 0 hits according to logs. To be sure I'll put the debugging options on again and let you know the results as soon as the problem occurs again. Are these enough?:

log4j.logger.com.xpn.xwiki.plugin.lucene.IndexData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.DocumentData=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexUpdater=debug log4j.logger.com.xpn.xwiki.plugin.lucene.IndexRebuilder=debug log4j.logger.com.xpn.xwiki.plugin.lucene.LucenePlugin=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResults=debug log4j.logger.com.xpn.xwiki.plugin.lucene.SearchResult=debug

You can use

log4j.logger.com.xpn.xwiki.plugin.lucene=debug

I think but AFAIK there is almost no debug log in Lucene plugin.

...

I haven't examined the code thoroughly so probably a missed shot but is

there any chance that this could be a method synchronization issue with searchers and writers?

Everything I could find was this one problem in closing the writer:

23:00:06,242 [Lucene index updating thread] [Lucene Index Updater] WARN lucene.IndexUpdater - Failed to close writer.

I forgot to mention another symptom suggesting index reading problems: when the situation is on I can do Lucene-queries (custom search page wo getQueueSize()) but it just doesn't return anything. So the plugin kind of "works" but "seems" not to be able to read indexes properly.

As far as i can see in the code all search* methods in the public api are "protected" from any Exception and return null when something wrong happen. But it also log the error so when you do a failing search you should have something in the log.

For your informations: as far as i can see in the code there is only one way to have the IndexUpdater to null (whichgenerate a nullpointerexcetion in #getQueueSize) is when during the init the index can't be opened. In this case you should find a log looking like this:

"Failed to open the index directory: " followed with a message detailing a little why it can't open index directory.

(so indeed it could be caused by the fact that no more inode can be used on linux for example).

Could you look if you can find this error anywhere in the log ?

Hello,

My issues seem to happen randomly but not at startup. Plugin works well from some hours to some days but I'm not sure what triggers this. I haven't been able to debug anything of interest in plugin's logs.

Only potential clue I have is that plugin is leaving index files open which -at least- leads Tomcat finally to "too many files open" -error at some point. lsof | grep "lucene" gives me a bunch of these:

... java.bin 10095 tomcat 666r REG 104,1 60931511 15634869 /srv/www/DATA/xwiki/lucene/_5r7.cfs (deleted) java.bin 10095 tomcat 667r REG 104,1 60931507 15634870 /srv/www/DATA/xwiki/lucene/_5r9.cfs (deleted) java.bin 10095 tomcat 668r REG 104,1 60931507 15634871 /srv/www/DATA/xwiki/lucene/_5rb.cfs (deleted) ...

...

Also, xwiki gets the plugin object normally during the malfunctional

state but it seems it just cannot read index. Could it be that the plugin becomes unusable not before a deleted index file becomes overwritten by the system? That could be the reason why the time it works varies so much (depending on the other file system usage of the underlying operating system)? WDT?

This one is http://jira.xwiki.org/jira/browse/XPLUCENE-30 but I don't see how it could be the source of the nullpointer exception issue.

Hi guys,

getting some informations since i can't find just at looking at the code how this would append.

When you have the issue, does it appending since the time you started XWiki or does it works and at some point it stops to work even if you did not restarted XWiki. Basically is it always a startup issue ?

And in that case do you have anything in the beginning of the log like a warning or something indicating that something wrong append during lucene plugin initialization ?
