gcj currently doesn't know anything about generics.  I'm working on a
new experimental gcj front end that will support generics and other
new features (static import, enum, etc), but it is pretty far from

Yes, definitely!  There's a lot to do for generics, both on the
compiler side and the library side; we have to look at doing
everything.  Ordering isn't super-important, as we need it all working
together in the end, before we can really release it.

I'd like to propose that we make a branch for this in the Classpath
cvs repository.  Then when we're ready for generics in the main line,
we can merge it all over.  I think we can't really put it in the main
line until the compiler support issue is solved for all the
participating VMs.

We'll probably have to talk about this a bit on the Classpath list,
but I don't really anticipate any problems.  Classpath as a whole is
pretty open to changes like this.
