Happens-before
Program order rule: Each action in a thread happens-before every action in that thread that comes later in the program order.
Monitor lock rule: An unlock on a monitor lock happens-before every subsequent lock on that same monitor lock.
Volatile variable rule: A write to a volatile field happens-before every subsequent read of that same field.
Thread start rule: A call to Thread.start on a thread happens-before every action in the started thread.
Thread termination rule: Any action in a thread happens-before any other thread detects that thread has terminated, either by successfully return from Thread.join or by Thread.isAlive returning false.
Interruption rule: A Thread calling interrupt on another thread happens-before the interrupted thread detects the interrupt(either by having InterruptedException thrown, or invoking isInterrupted or interrupted).
Finalizer rule: The end of a constructor for an object happens-before the start of the finalizer for that object.
Transitivity: If A happens-before B, and B happens-before C, then A happens-before C.
