             Summary: Corrupted Working/Production memory
                 Key: DROOLS-215
                 URL: https://issues.jboss.org/browse/DROOLS-215
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
    Affects Versions: 5.5.0.Final
            Reporter: Ales Dolecek
            Assignee: Mark Proctor


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
