a thread calling m2 could read through 0, 1234567890L, or A few other random benefit as the statement i = 1234567890L is just not certain to be atomic for a protracted (a JVM could produce the initial 32 bits and the last 32 bits in two operations in addition to a thread might observe i between).
Your assertion is only legitimate for architectures that give these types of promise of atomicity for shops and/or hundreds. You'll find architectures that don't Atomic make this happen.
