Without the <s:debug/> tag the application runs. When you insert the
debug tag the application gives you an HTTP 500 error and
you get the following stack trace in the logs.
The name of the application is ex81 and the name of the jsp is
claim-shirt-success. The same thing happens if you put the debug
tag on any jsp so it is not specific to this one.
