Looks like the purpose of these unit tests are to test the mock container itself; correct assumption? If so, we might be approaching a level of coverage to match that of MC. That said, there's absolutely a bug with the Mock SessionContainer in Proxy and your fix looks good. So green light for a commit on that piece at least. Also: * System.out.println == Bad. org.jboss.logging.Logger == Good (for these purposes anyway, it's a standard here, don't ask why another logging framework). Good stuff, finding all the proper code for bootstrapping an embedded EJB environment. Say the word and I'll assign you some of my recent backlog of issues for Proxy.
