DoesI have to worry RuntimeException throw by LRUAlgorithm.e

[hkdennis2k]

I am using JBoss with Hibernate(not .har package) and JBossCache.
But I notice that some error message appear randomly.
java.lang.RuntimeException: LRUAlgorithm.evict(): null node map entry for fqn: //com/mypackage/myobject

Jboss 3.2.6(with JbossCache included) Hibernate 2.1.8.

1.
Is it my fault of programming or configuration?

2.
It is a bug of JbossCache? just wait for the update and replace the jar?

3.
Does JbossCache still working while the error display? Wiil it crach my program? or it will reset itself and keep running well?

thanks
