Yes, I agree that Sandra's stuff is closer.  I would hope that with the 
ECJ conversion (planned for Stage 1), the Java issue goes away.  So, 
that would leave you with fixing the various other back-ends, which 
should be mechanical, but perhaps somewhat time-consuming.  I'd also 
hope that other folks would volunteer to help with some of that work, 
since getting it done will make the compiler more efficient, which is 
better for everyone.
