SwingBasher Reliability crash on Hopper Build 6 and 11

Configuration run :

OS : Windows 2000
Build : Hopper Build 06
VM : Client and Server

SwingBasher Test Suite is failing on Windows2000 for both Client and
Server VM on Hopper Build 06 and strangely exactly after 19 loops all
the cases . It stops after running 19 loops. We have tried running it on
different machines also .

The suite is available in our Workspace at :
/net/sqindia.india.sun.com/export/disk02/swing/workspaces/Merlin_int_ws/
In the directory Swing_Automated_Tests/Reliability,

Method to reproduce:

1. Set JAVA_HOME to Hopper Build 06
2. Set SB_TIMELIMIT to 2160 (36 Hours i.e.)
3. If running Server VM then Set the variable JAVA_FLAGS to '-server'
4. sh runnit.sh

I also ran SwingBasher test suite on :

OS : Windows 2000
VM : Client VM
Build : Hopper Build 11

I recieved the following error after 22 loops (Less than 3 hours) .

================================================================================
Please ignore the stack trace above , This would appear only when PopReltest01 was uncommnected . On running with PopUpRelTest01 commented out (Which should be the case ). I get OutofMemoryError after 19 loops.
