Multiple intermediate representations already exist for Java. I know
of the 'Spoon' metamodel, and the Eclipse Java DOM,
(sorry, I found no better link)
I've not used either yet, but I *think* both provide things like type /
variable resolution, in addition to actually parsing the code.
Unless, as Randall says, you've got to deal with more than just standard
Java syntax, I'd be looking at a pre-existing representation.
