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. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018416#...
