Then the NPE occurs at the following line: ---------------------8<--------------------- String emailAddr = (String) userObj.getProperty(XWIKI_USER_CLASS_EMAIL_PROP).getValue(); ---------------------8<--------------------- I think this could be caused by a XWiki.WatchListClass object, with a notifier set and watched stuff, in a page which is not a user (no XWiki.XWikiUsers object) JV.

Hi Jean-Vincent, it seems that, cleaning the bad objects, the error that i found in my logs is a very little different. here's what i get now: com.xpn.xwiki.XWikiException: Error number 3205 in 3: Version 7.1 does not exist while reading document Technical Experience Center.X6 miglioramento eliche girapacchetto versione in acciaio Test Specification at com.xpn.xwiki.store.XWikiHibernateVersioningStore.loadXWikiDoc(XWikiHibernateVersioningStore.java:220) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:1491) at com.xpn.xwiki.plugin.watchlist.WatchListEvent.getPreviousVersion(WatchListEvent.java:386) at com.xpn.xwiki.plugin.watchlist.WatchListEvent.getHTMLDiff(WatchListEvent.java:531) at sun.reflect.GeneratedMethodAccessor673.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.doInvoke(UberspectImpl.java:389) at org.apache.velocity.util.introspection.UberspectImpl$VelMethodImpl.invoke(UberspectImpl.java:378) at org.apache.velocity.runtime.parser.node.ASTMethod.execute(ASTMethod.java:270) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:252) at org.apache.velocity.context.ProxyVMContext.get(ProxyVMContext.java:222) at org.apache.velocity.runtime.parser.node.ASTReference.getVariableValue(ASTReference.java:829) at org.apache.velocity.runtime.parser.node.ASTReference.execute(ASTReference.java:212) at org.apache.velocity.runtime.parser.node.ASTReference.value(ASTReference.java:493) at org.apache.velocity.runtime.parser.node.ASTExpression.value(ASTExpression.java:71) at org.apache.velocity.runtime.parser.node.ASTSetDirective.render(ASTSetDirective.java:142) at org.apache.velocity.runtime.parser.node.ASTBlock.render(ASTBlock.java:72) at org.apache.velocity.runtime.directive.VelocimacroProxy.render(VelocimacroProxy.java:212) at org.apache.velocity.runtime.directive.RuntimeMacro.render(RuntimeMacro.java:247) at org.apache.velocity.runtime.parser.node.ASTDirective.render(ASTDirective.java:175) at org.apache.velocity.runtime.parser.node.ASTBlock.render(ASTBlock.java:72) at org.apache.velocity.runtime.parser.node.ASTIfStatement.render(ASTIfStatement.java:87) at org.apache.velocity.runtime.parser.node.ASTBlock.render(ASTBlock.java:72) at org.apache.velocity.runtime.directive.Foreach.render(Foreach.java:366) at org.apache.velocity.runtime.parser.node.ASTDirective.render(ASTDirective.java:175) at org.apache.velocity.runtime.parser.node.SimpleNode.render(SimpleNode.java:336) at org.xwiki.velocity.internal.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:196) at org.xwiki.velocity.internal.DefaultVelocityEngine.evaluate(DefaultVelocityEngine.java:161) at com.xpn.xwiki.render.XWikiVelocityRenderer.evaluate(XWikiVelocityRenderer.java:116) at com.xpn.xwiki.plugin.mailsender.MailSenderPlugin.sendMailFromTemplate(MailSenderPlugin.java:806) at com.xpn.xwiki.plugin.watchlist.WatchListNotifier.sendEmailNotification(WatchListNotifier.java:133) at com.xpn.xwiki.plugin.watchlist.WatchListJob.executeJob(WatchListJob.java:262) at com.xpn.xwiki.plugin.scheduler.AbstractJob.execute(AbstractJob.java:75) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:525) 2010-11-09 15:15:13,267 [DefaultQuartzScheduler_Worker-9] ERROR watchlist.WatchListPlugin - Exception while running job java.lang.NullPointerException at com.xpn.xwiki.plugin.watchlist.WatchListNotifier.sendEmailNotification(WatchListNotifier.java:84) at com.xpn.xwiki.plugin.watchlist.WatchListJob.executeJob(WatchListJob.java:262) at com.xpn.xwiki.plugin.scheduler.AbstractJob.execute(AbstractJob.java:75) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:525) java.lang.NullPointerException at com.xpn.xwiki.plugin.watchlist.WatchListNotifier.sendEmailNotification(WatchListNotifier.java:84) at com.xpn.xwiki.plugin.watchlist.WatchListJob.executeJob(WatchListJob.java:262) at com.xpn.xwiki.plugin.scheduler.AbstractJob.execute(AbstractJob.java:75) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:525) so it seems that the document "Technical Experience Center.X6 miglioramento eliche girapacchetto versione in acciaio Test Specification" doesn't exists, but it's not true, it exists and it's loadable from xwiki. version 7.1 too. i add that we swiched to XE2.5.32127, and the problem remains. any idea? i wonder: if during the job occours an error on a document, the entire job fails? would it be possible to handle the exception, maybe sending a notification mail to admin users for that particular problem, and let the job continue its work?
