I'm using JBPM 3.3.1 GA and Jboss 4.2.2 GA

This Exception is thrown when my ActionHandler is called( i tried with enter, leave, transition events), and on any process token. 

I have a simple process with start state, middle state, end state.
And i have an Handler when the middle state is reached.


Anyone can suggest me which class have a bad version id or how i can have more details?
Becasue the primary problem is that i don't understand which class have a bad version, the exception don't advise me on which class has this problem.

Thanks in advance
