[rules-users] java.lang.LinkageError, but only sometimes

[Mattias Nilsson Grip]

I'm guessing now. But since the stack trace includes org.drools.rule.JavaDialectRuntimeData I would rather say it is related to Java and not to MVEL. Actually org.drools.rule.MVELDialectRuntimeData seems to have less class-loading logic than JavaDialectRuntimeData so if this is indeed a bug a workaround may be to switch from java to mvel dialect. Another workaround could be to "warm up" your rules by firing them from a single thread before exposing the knowledge base to the multi-threaded client code.

Regards,
Mattias

Thank you for your reply.
I have created the following issue:
https://issues.jboss.org/browse/JBRULES-3675

We are now running the same setup on 5.5.0.CR1 and so far, we haven't
encountered the linkage error. Could this be related to mvel?
