It seems to be a jikes bug. But it is also a gcj bug (after a comment in=20
SocketImpl.java & DatagramSocketImpl.java in classpath's source) that=20
classpath solve by redeclarations of "setOption" and "getOption" methods=20
in the 2 mentioned classes.
If you decide to do the same thing than in GNU Classpath, don't forget=20
the DatagramSocketImpl (it has the same problem but this is not shown=20
with regression tests).

As the problem may be reproduced in other cases, I join a file that can=20
be put in test/regression, or at least that shows you the bug. It works=20
with kjc, but not with jikes 1.17 (it compiles but throw a=20
"NoSubMethodError" exception. I called it "AbstractInterfaceTest"=20
because there is a problem with jikes when an abstract class implements=20
an interface. It may be renamed or thrown out if you think it's bad idea=20
(that is NOT a kaffe bug)

Best regards,

PS: I encounter a "bug" when I post something to kaffe's mailing list :=20
I receive my post 5 hours after I posted it. I believe this is because I=20
live in France and there is a 5 hours shift between Eastern USA &=20
Western Europe. How could this be "repaired" ?
