The problem has been fixed with latest kernel 2.6.12-1.1387_FC4. So it wasn't a swing bug; moreover it fixes the eclipse hang bug and many other random hangs. Thank you anyway :)
It still crashes with the latest kernel-2.6.12-1.1398_FC4: $ logfactor5 /usr/share/java-utils/java-functions: line 117: 22618 Segmentation fault $JAVACMD $FLAGS -classpath $CLASSPATH $OPTIONS $MAIN_CLASS "$@"
For what it's worth, I'm running kernel-2.6.12-1.1398_FC4 and I see the same stack trace as Comment #2.
it also segfaults with the latest kernel-2.6.12-1.1420_FC4
Lillian, will you see if this Swing bug is fixed in GNU Classpath HEAD?
Runs fine on Classpath+jamvm jamvm -classpath /usr/share/java/log4j.jar:/usr/share/java/xml-commons-apis.jar:/usr/share/java/jaxp_parser_impl.jar org.apache.log4j.lf5.StartLogFactor5
Great, I'll wait until the fixes make their way into Rawhide via libgcj before closing this bug.
