The Class Loading Architecture document on SF Docs section (http://sourceforge.net/docman/?group_id=22866) explains the usual reasons why CCE occurs from Java's Runtime System.

If this occurs with the most recent bug fix version of JBoss and you believe it to be a bug, submit it to the bug tracker. Attaching a reproducible test case will help.

Actually I can't find the CCE reference now, I must have been dreaming...

I may have experienced the same thing w/ 3.2.2RC3; I submitted a bug report (#795782). Sorry, the code that produced this is too complex to produce a simple test case, partic. since the problem does not repeat regularly.

I'm getting this error too. Random ClassCircularityError's in the oracle jdbc drivers. Any ideas what is causing it?

We used to get this error when the Server wasn't getting Shutdown properly.

In case the Shutdown is not normal, just delete the Default/tmp folder. and then restart the server. This seems to have solved my problem
