Yes, and thanks for doing this.  I'm having some trouble seeing the
problem spots clearly.

I've been thinking a bit more about the test suite.  I think we should
probably delete libjava.compile entirely -- it is a collection of
random regression tests for the gcj front end, but now that that is
gone, this stuff isn't too useful.

As for the rest I suppose we can check in jar files and use those.
