Just thinking out loud here. Don't mind me.

Intercept the constructor. Instead of just returning an instance, look up from the 
pool (say an ArrayList) the first unused instance. Set a flag to say it's in use and 
return the instance.

Intercept the finalize(). In the AOP-all example there's an extra set of 
"Entering../Leaving.." output, so maybe it's using the finalize or something. That's 
really the closest thing we have to a deconstructor in Java, which should be fine, 
since that's where you're supposed to close any resources anyways.

Figure out what to call when a method is called. Should we directly call the method on 
the object? The idea that JCA uses is that of handles, so you're never directly 
pointing to the actual resource object.
