It's very 0N/A difficult to synchronize properly here so we wait for the 0N/A semaphore, then wait a little longer for the mbs.invoke to 0N/A run, then just in case that isn't enough, we wait for the 0N/A thread to be in WAITING state. This isn't foolproof, 0N/A because the machine could be very slow and the 0N/A Thread.getState() could find the thread in WAITING state 0N/A due to some operation it does on its way to the one we're 0N/A // Thread 2 - try to add a listener 0N/A /* Wait for Thread 2 to be blocked on the monitor or to 0N/A for (
