Hello all,
I wrote the attached class that runs fine on Sun's JDK. However, when I
run it on Kaffe I get the error at the bottom of the email. It freezes
at the exception and the Frame is never displayed. I have to crtl-c out
of it. If I simply comment out one off the drawButton() calls it works
fine in Kaffe. I tried the latest cvs code, tried binaries compiled
against both kaffes and sun's sdk and I even tried using jikes with
kaffe's bootclasspath. I assume its some kind of garbage collection
issue. Any insight would be helpful
