Hi,

When using JbossCache in Tomcat 5.5 with JOTM as the JTA transaction manager, I stumbled upon a memory leak. After investigating with a profiler I noticed that an object I removed from JbossCache kept being referenced by a org.jboss.cache.marshall.JBCMethodCall, which was via among others a org.jboss.cache.TransactionEntry being referenced by a org.objectweb.jotm.SubCoordinator.

I'm using JBossCache in the typical way:

TreeCache treeCache = new TreeCache();
PropertyConfigurator config = new PropertyConfigurator();
config.configure(treeCache, "META-INF/treecache.xml");
treeCache.startService();

UserTransaction tx = (UserTransaction) new GenericTransactionManagerLookup().getTransactionManager();

tx.begin();

treeCache.put( "/test" , "foo", someTestObject );

tx.commit();

treeCache.removeData( "/test" ); // extra, for test
treeCache.remove( "/test" );

treeCache.stopService();
treeCache.destroyService();
