Note this is _assignment_ not arithmetic. Depending on the capabilities of the underlying hardware (and the cleverness of whichever JIT your JVM uses), even a simple incrementation may not be atomic. Such an action may require a memory read, addition within the CPU, and a memory write; preemption may occur between the read and write, causing the results of the incrementation to be questionable if not synchronized. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
