NullPointer when running test

Hello all - Here's the situation - hope you can help.

Wrote a faily simple Test Plan:
 Thread Group
    Request defaults
    Cookie manager
    Page request
    File reporter

The request is being made to a secure(https) jakarta web server for an
login.jsp that performs a strut action.  So, my server is set up to
"secure.myserver.com" with the path "/pathname"  then in the Page request, i
request "/login.jsp".  The Thread test sequence is 5 threads at 2 loops.
When I start the test, it appears to run fine in the console window
displaying the program output.  Below is the output of the program:

Sampling url: https://login.providerlink.com/login.jsp
Sampling url: https://login.providerlink.com/login.jsp
Sampling url: https://login.providerlink.com/login.jsp
Sampling url: https://login.providerlink.com/login.jsp
Sampling url: https://login.providerlink.com/login.jsp

>From the looks of it, it samples the URL the first 5 times without a
problem, but then you get the NullPointer on the second set of threads.  The
onlything written to the file reporter is as follows:


# Sample data created by null

#       URL                    Milliseconds

So, that's my quandry.  Any insite into this would be most appreciated.
