JBPM and Drools 6.2.0 Final throws java.io.OptionalDataException when deepClone is invoked in org.drools.core.util.ClassUtils when high concurrency

The exception randomly occured in some threads while more than 2 dozens of them running concurrently.

java.lang.RuntimeException: java.io.OptionalDataException

We recently upgraded to JBPM and DROOLS 6.2.0. We used 5.5.0 which didn't have this problem when running high concurrency.

Has anyone encounter this issue?

Today we encountered what seems to me the very same error. We do use 6.1.0 Final and received the following

In addition to my previous reply, we even have a more detailed root cause:

Once again, under heavy load, we have yet another almost similar exception (Drools 6.1.0.Final)
