Description

When the multithreadtest case is run on a Hyper Threaded CPU machine, it fails sometimes. One in 3-5 runs results in a failure. Failures are not seen when run on a non-HT machine. The exception trace is as below:

<testcase classname="test.wsdl.multithread.MultithreadTestCase" name="testMultithreading" time="5.664">
<failure message="Throwable caught: java.lang.NullPointerException" type="junit.framework.AssertionFailedError">junit.framework.AssertionFailedError: Throwable caught: java.lang.NullPointerException
at test.wsdl.multithread.MultithreadTestCase$Run.run(MultithreadTestCase.java:103)
