Some real kernel developers might have better insight on why this happens.
But this hits APIC timers during a syscall. I would probably try to boot
the box with 'noapic' in the kernel command line, to see if this improves
things or not.
Do you see the "soft lockup - CPU#0" always? or does it also happen to
other CPUs as well? And if it does, is the java process running on more CPUs?
