Trying to set up TreeCache for performance testing, and encountered the 
following error.

Changed Hibernate to the latest release 3.2.4 sp1 and swapped in its associated 
treecache. Same error occurred under both JBOSS 4.0.5 and the latest 4.2.0.

Changed Treecache to 1.4.1 sp3. The error persists. What could be the problem.

Ehcache worked fine in all scenarios.
