[jboss-jira] [JBoss JIRA] (DROOLS-215) Corrupted Working/Production memory

[Mark Proctor (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12814418#comment-12814418 ] 

Mark Proctor commented on DROOLS-215:
-------------------------------------

"I wish I could spend time building a test case, but it would take us quite some time to setup a unit test on this issue."
Could you paste the rules? or the offending rules? There is nothing in that stack trace that can help us, you need to unwrap it to see what he root exception is.

> Experienced ClassCastException mixing BetaMemory and AlphaMemory. There is debate in the mailing list/forum. The problem seems to be related to dymanic updates of knowledgebase.
> Saddly there is no deterministic way how to reproduce the issue, but that should not prevent tracking it here.
> Stack trace from my project:
> java.lang.ClassCastException: org.drools.reteoo.BetaMemory cannot be cast to org.drools.reteoo.AlphaNode$AlphaMemory
