Description David McCann CLA 2010-07-15 15:47:44 EDT 
We currently cache helper contexts for JBoss on the archive file name, and we also keep a map of archive file names to class loaders. During lookup, if we find an existing entry in the map for a given archive file name we compare the loaders to determine if a redeploy has occurred.  This method of detecting a redeploy is not acceptable.  The problem is that if the context loader is changed during application execution (which can and does happen) such that we cannot locate what we consider to be the application loader we assume redeploy and wipe the entry from the map.

We need to register a listener with the JBoss MBeanServer so we can be notified of a redeploy.
