Jeremy Whiting updated AS7-3276:
--------------------------------

    Steps to Reproduce: 
Attach a debugger to the AS7. Wait for the server to start. Add an exception breakpoint for java.lang.NullPointerException
Use a browser to request a resource in a deployed web application. The debugger will trap on the NPE in the valve.

>  With a debugger attached to AS7 I am seeing a NullPointerException thrown in a JBoss implementation of a Valve. This happens on every web request that does not have a principle in the session. The exception type has never appeared in logs because it is caught and a generic message is displayed. 
>  This affects the performance.
>  Also the class uses the debugf logging method in the catch block. But does not pass in a format. A format is expected as the first parameter to the debugf method.
>  Included with this JIRA is a patch to change the code so that null references are detected. The second change changes the logging method call to instead use debug. Whether it should be a error message rather than a debug is a different matter and this JIRA does not tackle the question.
