    Strange Exception (6.0.0.M3)  What is it?

    Greg Zoller Newbie

      Hello,

       

      I am getting a very strange exception and I don't know what/why I'm getting it.  Exception is below.

       

      Basically I have a trivial EAR file, which contains a WAR.  In the WAR is a ServletContextListener that starts a Scala Actor (essentially a thread) that fires periodically and calls a local EJB method to a stateless session bean.  Pretty harmless stuff, and it works great... for a while.

       

      After running for some time (maybe 15-20 minutes?) I get the exception below.  The exception also kills my Actor so the calls to my session bean stop at that point. 

       

      I'm seeing logging stuff in the exception, as well as a lot of transaction stuff--rollbacks, etc.  (I'm not explicitly creating/using any kind of transaction (I'm not even using persistance)...can't say what's going on automatically in the background though.)

       

      Googling around gave me a hint this may have something to do with passivation, and that might explain why it runs fine for a while, but I really don't know.

       

      Any ideas welcome.

      Thanks!

      Greg

          Also from what I remember, JBoss AS 6.0.0.M3 had some transaction related bugs which I think have been fixed in the latest released JBoss AS 6.0.0.M4. You might want to upgrade to M4.
