Yes, there is the following failure:
FAIL: gnu.testlet.java.io.PrintStream.subclass (number 1)

That test tries to set the protected out variable (of the
FilterOutputStream superclass of PrintStream) and then use it normally.
Which fails with this new PrintWriter delegate thing.
Tricky to get right...

What is the problem? I just checked in a little fix to make mauve work
with gcj (native standalone) again.

I would loose the synchronized on the write methods. The original libgcj
implementation didn't have them and I don't believe the PrintStreams are
guaranteed to work deterministically when used from multiple Threads.
