No, it was _not_ java that failed. The kernel was spinning instead of
scheduling threads. Any threaded application would have triggered the
kernel bug - or a usleep() call from a non-threaded application. By
the time I got the call I was able to google the fix about resetting
the date, but the guys who manage some SuSE systems started earlier
and ended up rebooting some of them - and they don't run java
applications.
