[jboss-user] [JBoss Seam] - Seam Unit tests random ConcurrentModificationException

[wiggum14]

Hello,

I'm sure someone is going to tell me to post this to the Embedded JBoss forum, but I decided to try here first.  Sometimes, rather randomly, my unit test fail with a ConcurrentModificationException.  The stack trace looks like this:

It appears to fail while attempting to deploy one of my annotated beans.  This exception occurs when I'm running my unit tests within Eclipse or running all of the unit tests using Maven.  

Thanks.
