The choice is arbitrary and any one of the 4 threads may be woken up. The intrinsic lock in java is not fair which will cause some of the waiting threads to wait longer than others even though they attempted to gain the lock first. A ReentrantLock can be used to grant access to the longest waiting thread if this matters for your program.
