So why do we talk then about N locks on the same object?
In method A.m3(), Thread-1 performs 3 unlock actions on the A object and Thread-2 performs 2 unlock actions on the A object.
Why is a boolean logic not good enough?
The first thread performs 3 lock actions, returns from m3, m2 and m1. Then the virtual machine can release the lock.
The second thread performs 2 lock actions, returns from m3 and m2. Then the virtual machine can release the lock.
