Mario Fusco commented on DROOLS-5190:
-------------------------------------
I tried to reproduce this problem inside drools with the unit test that I'm pasting at the end of this comment but with no luck. I understand that you anonymized your data, but I fear that we also lost some relevant information doing so.
The unit test below mimic inside the engine, exactly what you described. Please try to reproduce your problem by manipulating it with data as close as possible with production-like ones. If we cannot reproduce the problem in this way I don't see how I could further investigate this issue.
One last note. Is there any reason why you're using events processing? I don't see anything related to temporal reasoning in your rules. Is it something else (also possibly relevant) that you cut in your rules sample?

> Key: DROOLS-5190
> URL: https://issues.redhat.com/browse/DROOLS-5190
> Project: Drools
> Issue Type: Bug
> Components: kie server
> Affects Versions: 7.18.0.Final
> Reporter: Minal Bhalodi
> Assignee: Mario Fusco
> Priority: Major
>
> We are seeing ClasscastException while evaluating kie rules. Everytime we see this issue we have to restart the server to fix it.
> This doens't happen to all our kubernetes pods where same kie-server is running. This happens to either 1 or 2 pods all the time.
> This issue is also not reproducible
> Also we see different stack Trace with ClassCastException every time, Here I am pasting some of them:
> ERROR 1 :
> [className=DroolsKieContainerCommandServiceImpl]- Error calling container 'kie_personalization'java.lang.ClassCastException: null
> ERROR 2:
