Enthuware

The thread that has called the wait() will not come out of WAITING state until some other thread calls notify or notifyAll on the same object or interrupts the thread.

As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:
synchronized (obj) {
while (<condition does not hold>)
obj.wait();
... // Perform action appropriate to condition
}
