ConcurrentModificationException in Seam unit tests with Embedded JBoss
I know this is not the best forum for this post, but I figured I'd see if anyone knew of a good workaround.
I've been getting ConcurrentModificationException almost every time when running unit tests in Embedded JBoss beta3.SP5. It looks like it comes from Domain in JBoss AOP. Someone suggested a workaround to undeploy/redeploy until it works, however this actually doesn't work because the MDBs don't deploy the second time.
Here is the stack trace:

Anyone have a better workaround? I'm trying to see if I can just patch org.jboss.aop.Domain, but I can't figure out how to get that into the embedded jboss jars or even where to get the source code.
