Why is jgroups required even in LOCAL mode? Basically because JBC is very tightly coupled to JGroups.  In 1.x, TreeCache is actually a subclass of the JGroups RpcDispatcher (not in 2.0, but RpcDispatcher is still imported). From that, the class that represents an invocation through the JBC interceptors is a subclass of a JGroups MethodCall.  The JGroups View class pops up here and there too.

There's a JIRA to eliminate the coupling but IIRC it's not on anything but a long term roadmap.
