-----------------------------------------------------------------

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?
Could you at least post the full stack trace, so that we can see the root exception?
Thanks

> 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.

> java.lang.ClassCastException: org.drools.reteoo.BetaMemory cannot be cast to org.drools.reteoo.AlphaNode$AlphaMemory
