[JSR308] Javac Processor API

Yes, I left out the Enter pass for simplicity, but it is important  
and so I should not have.  However, as I understand it, the Enter  
pass only derives information for the "interface" of a class: i.e.,  
the types of its fields, method parameters, and the like.  It does  
not look inside of a method, right?  Therefore, even if this pass has  
executed, attribute processors still will not know (for example)  
whether "foo.bar" represents a package, static field reference, etc.

Anyhow, most likely this issue is out of scope for JSR308, but I  
wanted to raise it in any case.
