Known bug, I just don't know how to fix it, my shell scripting skills are not
31337 enough ;) Please take a look at the class file compilation bit in
libraries/javalib/Makefile.am. Maybe you can come up with a way that prevents
the creation of rt.jar when a compilation in the for lop fails. Currently it
just proceeds ...

done.

added to kaffe's test suite.

go ahead, Mauve hackers always welcome new tests.

Mauve is the "cross-vm" compatibility test suite. It contains a ton of tests
for different aspects of class library functionality. Kaffe (and other VMs)
also usually have regression test suites to quickly detect resurfacing of known
bugs. It comes down to different purpose, different test suite. 

That being said, it would be nice to port some regression tests into
functionality tests for Mauve. I've been offered write access by Mauve hackers,
but I didn't have any time to undertake that task, so I turned that offer down.


If there is some interest in getting tests from kaffe into mauve, I could act
as a proxy. But I would prefer that someone else plays that role, since it's
better to spread out responsibilities. ;)

cheers,
