Refactorings for JBC2.2 (JBCACHE-1222)

[mircea.markus]

There are some code refactoring ideas being discussed, which would have impact on JBossCache core architecture. We've set up an wiki with our observations here:
http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheRefactoring22
Any suggestion/observation on this is welcomed!

I've updated the wiki a bit, added some links to the JIRA, attached the UML diagram, etc.

As a comment - could we replace the ZIP archive with a patch file? Easier to view diffs, etc.

Should also discuss how the old Interceptor.invoke(InvocationContext ctx) interface is dealt with, since custom interceptors will extend Interceptor.

Ok I had a think about the Commands being immutable, at least by the Interceptors - won't work. There are some Interceptors that change the parameters of the call, such as the MarshalledValueInterceptor that wraps and unwraps payloads as MarshalledValues.
