If lastRequestId is a long, then it clearly is not.
I don't think that it is in general either...not sure
if that changes with hotspot. And while it may be
under certain VMs, I don't think that you can generalize
that.

Subject: [JBoss-dev] is x++ an atomic operation??
Date: Thu, 18 Jul 2002 08:54:43 -0400
Quick question for you Java Language Gurus out there, I heard
one that the post increment operator was an atomic operation.
For example, if you have a multi-threaded application with:
id=lastRequestId++;
You would not need to put this in a synchronized block be cause
the ++ would be atomic and thus you would not get 2 duplicate ids.
I was wondering if this is true or not. Can anybody confirm this
for me??
Regards,
Hiram
