Using Mozilla 1.4 with the java plugin on s10_38

page% java -showversion
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)

An applet loads on http://viseng.sfbay that, when I try to close the page, sends the java_vm process into a spiral. The process starts to eat up an entire CPU and locks mozilla. I have to kill the java_vm process, with takes mozilla with it, in order to start working again.

Stack trace of the java_vm process is attached but one odd thing is that the java_vm process was spinning on NLWP #22 according to prstat but that thread isn't in the stack trace.

   PID USERNAME SIZE RSS STATE PRI NICE TIME CPU PROCESS/NLWP
  9774 tmcmahon 138M 39M cpu0 0 10 0:08:46 95% java_vm/22

Note also that killing mozilla doesn't fix this. You have to nuke the java_vm process. I've also attached a truss output from the java_vm process for a few seconds.

To reproduce the problem I bring up mozilla 1.4. Go to viseng.sfbay and an applet loads. Click on one of the links on the page......hang.
