test program

Version: 3.6.2
Build id: M20110119-0834


I got the following exception while going through the http://wiki.eclipse.org/Debug/Test_Script#Stress_Tests manual test and using the TestManyThread.java test program (attached).  I saw the exception only once though and I wasn't able to reproduce it.

java.lang.NullPointerException
