[jboss-user] [JBossCache] - Re: Strange ClassCastException in OptimisticCreateIfNotExist

[spennec]

Hello Manik,

Here is what I hope will help you. Since I'm not too knowledgable about TreeCache's internals, I selected a few logs that I thought were representing of the situation just before the exception.
