-------------------------------------
I don't know what is the best strategy for this particular exception handling, but
logging debug is not good when you get an unexpected throwable. Normally, if you get that,
the exception falls through, the request will fail, everything is recycled, and the user
gets disconnected.
NPE thrown in SecurityContextAssociationValve.

Key: AS7-3276
URL: https://issues.jboss.org/browse/AS7-3276
Project: Application Server 7
Issue Type: Bug
Components: Web
Affects Versions: 7.1.0.CR1b
Environment: On any platform running Java.
OpenJDK 6.
Reporter: Jeremy Whiting
Assignee: Remy Maucherat
Labels: patch
Attachments: npe-valve-logging-patch.diff
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.

Jeremy
