#497 jcaopool proof-of-concept

[Steve Lewis]

The idea is to intercept the constructor and retrieve
the object from a pool without the client knowing about
it, using AOP.

I'd like to do more testing, and have it set the
pointer to null if I can do that after calling .close();

I had to delete the lib jars to attach, so just copy all the
AOP beta 1 jars into the lib subdirectory to build.

src with bulid.xml and jcaopool.war for simple test
