--------------------------------------------------------------
I am using a Hibernate 3.1.13 with jboss-cache 3.2.5
I'm running my application with second level caching enabled and in middle of the
application (based on user operation ) I am closing the existing session factory
(sessionFactory.close();) and create a new one.
Up to this moment my second level cache work fine and after closing and creating new
session factory I am getting following error from the Treecache.
Error
