Please do try to narrow down the root cause if you have time. The
major change in GL4Java between JDK 1.3.1 and 1.4 is the use of
the JAWT for acquiring the native window handle. If the code
which uses JAWT doesn't handle all of the error cases properly
then that is probably the source of the problems.
