That's just jikes complaining about a hack in AWT library code. The code=20
should work nevertheless.

I haven't tried the latest jikes from CVS yet, I'll do it today.

Compilers that work for me:
* jikes 1.14
* kjc 1.5b (has other serious bugs, though).
* javac 1.3.1

Compilers that don't work for me:
* javac 1.4.0 : make check fails almost all tests since the warning about=
=20
changed class file format version is not expected by the tests :) May wor=
k,=20
but will generate lot of "assert is a keyword now" warnings during=20
compilation.
* kjc 2.1A : miscompiles CatchDeath (and a few other tests), so that it f=
ails=20
to verify on JDK. since kaffe's verifier doesn't recognize the error, kaf=
fe=20
proceeds and does weird things.
* gcj 3.0.4 : fails to compile Klasses.jar due to a bug in gcj.
* javac 1.1.8 : fails to compile Klasses.jar due to bugs in javac.

C-Compilers:
I use gcc 2.95.3. My experience with gcc 3.0.4 was mixed : kaffe compiles=
, but=20
I get more failed tests. I didn't have time to investigate.

Failing tests:
Some tests have really tight watchdog timer settings. They will fail if y=
ou=20
are using a six year old computer, running KDE 3 alongside, and running k=
affe in=20
interpreter mode, like I do right now :). I've attached a patch that exte=
nds the=20
timer on watchdogs that used to fail for me.

Finally, each failing test has a testclass.out and testclass.fail file wi=
th=20
the expected output and the output of the failed attempt. Inspecting thos=
e=20
files might provide more insight at what exactly is failing.

hope this helps
