Davide Sottara commented on DROOLS-215:
---------------------------------------

wait a second.. this is a different CCE... it seems an exception in the RHS of one of your rules.
It's different from the internal CCE reported in this ticket. Can you check that?

> 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
