Description
Browser Crashes/ Hangs while reloading multiple Arc Test applet using Java script.

Reprdoucible Builds : 6.0u1 build 04. Not a regression this is reproducible even with 5.0u12b01. But with 6.0u1 browser hangs at much faster pace.

M/c tested : 
OS: Windows XP Build 2600 Service Pack 2  512 MB RAM

How to reprdoce:
Please unzip the attached TC4_01.zip 
unzip this to your Application Server. (in tomcat  <Tomcat Home>/webapps/ dir)
Load the page  http://server-name:port/TC4_01/TC04-01_Top.html Page
Set the interval as 2000 
Click on Launch on Multiple times. (may 2 or 3 enough)
Browser will crash or hang with in 1 minutes using 6.0 in 5.0 in 2 minutes.

Surprisingly If I put -verbose in the argument It is not hanging.
Attached the hotspot crash log for 6_0u1. (Crashing only once in a while but hang is reproducible).
Comments
EVALUATION This problem seems to be addressed in 6u4 with Hao's fix for 6399750 (RFE: Improve applet lifecycle and LiveConnect support in Java Plug-in.) We can no longer reproduce this problem with our 6u4 build. Fix was verified by Hao and myself. Change CR to duplicate of 6399750
