Need to add integration tests that confirm that JBossCache works properly with JBoss TM as its transaction manager. The standalone cache unit tests use DummyTransactionManager, as use of JBoss TM requires the app server. Beginning with 4.0.4, the AS web-tier state replication tests also no longer use JBoss TM.

See http://www.jboss.com/index.html?module=bb&op=viewtopic&t=76306 for an example of the kind of thing such tests should find.
