OK.

Let me report another problem though: very recently (3 days ago), 22 Java 
failures have been introduced on SPARC (44 for a multiarch compiler):
  http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg00389.html
  http://gcc.gnu.org/ml/gcc-testresults/2005-04/msg00508.html
on 4.0 branch.

I've never seen these failures, they are brand new problems.  As I've never 
debugged interpreted Java tests, I'm a little at a loss, but I think the Java 
compiler might be miscompiled (I recompiled libjava a few times with rebuild 
but not bootstrapped compilers and didn't get the failures).  I'm currently 
trying to pinpoint the patch.

What's your position on this?
