FWIW, it looks like the trouble comes from
hotspot/src/share/vm/prims/jvmdi.cpp because monitor->monitor().raw_notify
(or raw_wait or raw_notifyAll or raw_exit) is returning
ObjectMonitor::OM_ILLEGAL_MONITOR_STATE.
That seems to be triggered from
hotspot/src/os/bsd/vm/objectMonitor_bsd.cpp like this:
int ObjectMonitor::raw_notify(TRAPS) {
if (THREAD != _owner) {
return OM_ILLEGAL_MONITOR_STATE;
}
So at first glance it looks like a thread ownership problem. Don't have
time to dig any deeper ATM.
