Getting exception while running the tests

Hello,

We are having a test suite where we are testing the output of our jsp
taglibs. The tests are coded as testXXX() and endXXX(
com.meterware.httpunit.WebResponse).

The problem i'm facing is - individual tests pass without any error/failure.
But when I run the tests as a testsuite, I'm getting the following
exception. Also, the popping of this exception is not regular. I get this
exception when run on my laptop, but not get the same when run on our test
server:

Can anybody help me in identifying the cause of this exception?
