I have an MBean that I was deploying successfully on 3.2.2. I've had to switch to 3.2.5 to fix a CMP problem that I am having and now my MBean won't deploy. My MBean implementation class throws an exception and that exception is packaged in the same SAR as the MBean code. I'm not using classloader repositories or anything like that.
The SAR is packaged in my EAR with some common libraries and has a jboss-service.xml file inside.
