Game runs fine in sun jvm, microsoft jvm causes 99% cpu usage and is SLOW

Question

In the microsoft JVM (my target platform) I get 2 frames per second... in the sun JVM I get at least 60.
The strangest part, is that this only repros when iexplorer.exe is the only process running java anything... for example, if I have net beans running, I get 60 FPS in the microsoft JVM as well. That makes no sense to me.
I have tried thread.yeild and thread.sleep in my main loop, and that didn't fix anything.

I have tried thread.yeild and thread.sleep in my main
loop, and that didn't fix anything.About these 2 methods.
sleep() // example in almost every book. Leaves
// Thead on the schedule list
yeild() // Pell mell as in no control of when it unyields.
// prone to race/deadlock UNLESS monitored by
// another thread that wakes up periodically.
Tony's "Theorized" <- make the uptight acedemic sycophants happy.
Law of the exec constant.
"Any Thread or process *that locks the system MUST yeild controls for at
least 20MS pre iteration."
Why 20MS? It gives the underlying OS a little slice and is enough
to ensure everything gets enough CPU. Every MS under 20 increases
the deadlock potential. (*If at zero wait you get a preempted deadlock)
You can play with this value but I have found it is pretty consistent
across CPU speeds / hardware/
Use a synchronized wait() in your main run method every iteration.
Objet waitObject();
synchronized(waitObject)
try
   waitObject.wait(20);
catch(InterruptedException ie)
}wait() Removes the Thread from being scheduled.
This iwll give IE the CPU it needs and your CPU should dro
to around 1%.
