Hello,
<br>Last week, I checked out XWiki-platform trunk and tried to compile it with maven-2.1-SNAPSHOT and all the needed memory. 
<br>If I remove xwiki-core/../plugin/lucene, it works but with it, it fails.
<br>Before going deeper, I would like to know if anyone has already seen such issues?
<br>I get the following logs (lucene2.3 is in my MVN repository):
<br>.......
