Java Version: 1.6.0-b58
Platforms: SunBlad2000 with 2 cpus 900Mhz, 2048 Mb
Host name: soda.sfbay

Problems:
When running Java2Demo with -runs=10 -delay=5 -ccthread -zoom,
got exceptions, it always reproducible with the demo which is bundles with the jdk.
but it hardly reproducible with attached Java2Demo which Blessan has some fixes.

File a bug for tracking the problem in the future.
It only happens in solaris-sparc 10 with two cpus.

How to reproduce:
1. go to java promotion site, run Java2Demo.jar by:
bin/java -d64 -jar Java2Demo.jar -runs=10 -delay=5 -ccthread -zoom
2. If the demo within the jdk, it always reproducible.
if use attached demo, it hardly reproduce, but got exception once.

The exceptions as followings:
bin/java -version
java version "1.6.0-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-ea-b58)
Java HotSpot(TM) Server VM (build 1.6.0-ea-b58, mixed mode)
