Summary

0004661: JMX counters not as accurate on SPARC/Solaris

Description

Looked through code. JMX counters use integers and do not synchronize. They feel on Sparc that it will do a read, modify, change, while an Intel processor will do an inplace modify which will be atomic. Thus, they feel that the counts will be off on a Sparc, but not on an Intel platform. They use a Sparc platform.

Spoke to Scott. He plans on solving this with AtomicInteger in JDK 5 and above. Should be an easy fix.
