Re: [rules-dev] NPE in AbstractWorkingMemory.update

Hey Greg, please do open the JIRA. Thanks Edson 2009/5/27 Greg Barton <greg_barton(a)yahoo.com <mailto:greg_barton@yahoo.com>> At seemingly random times I'm getting this exception: Exception in thread "Thread-5" java.lang.NullPointerException at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1387) at org.drools.common.AbstractWorkingMemory.update(AbstractWorkingMemory.java:1350) at org.drools.concurrent.UpdateObject.execute(UpdateObject.java:46) at org.drools.concurrent.CommandExecutor.run(CommandExecutor.java:78) at java.lang.Thread.run(Thread.java:619) I've only gotten the exception when using StatefulSession.asyncUpdate() from a separate thread. AbstractWorkingMemory.java:1387 is wrapped in an if statement that checks whether maintainTms==true, so setting that to false has apparently avoided the problem. (Can't be 100% sure, but it has been runnign for a few hours without exception.) The FactHandles I'm passing in to StatefulSession.asyncUpdate() are never null, so I can only guess that InternalFactHandle.getEqualityKey() is sometimes returning false. Do you want a JIRA on this? I can't recreate it reliably. _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org <mailto:rules-dev@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/rules-dev -- Edson Tirelli JBoss Drools Core Development JBoss, a division of Red Hat @ www.jboss.com <http://www.jboss.com> ------------------------------------------------------------------------ _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
