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
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

Remy Maucherat commented on AS7-3276:
-------------------------------------
Casting a null object does not cause a NPE. The NPE will only occur if there's no
session.
Since right above, there's session = manager.findSession(hsession.getId()), a if
(session != null) should be enough.
I'd suggest removing the big try/catch(throwable) and logging a debug info. That's
not funny.

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.

-------------------------------------
Yes I see what you mean. I will add only a null check for the session.
Shouldn't the catch block be logging an warn instead of debug or info ?

Remy Maucherat commented on AS7-3276:
-------------------------------------
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.

A pull request has been created. I have omitted to change the level of the logging. To
avoid having users seeing warn messages that can be confusing as to severity of the
message. Instead I added a TODO to highlight it needing a decision later.
