HttpServletRequest.getServerName() occasionally returning null in concurrent use?

webservice

Under JBoss 4.0.1SP1, I have a servlet that makes multiple, concurrent calls to web services that are running under the same instance. I'm using request.getServerName() (on HttpServletRequest) to construct the endpoint URL. This normally works fine, but every once in a while returns null.

I hadn't seen this before running the web service requests in parallel, and so I guessed that sharing the HttpServletRequest among threads won't always work or something.

Any ideas on fixing this?
