I think I have fixes for both these issues.
https://github.com/wildfly/wildfly/pull/6539/files
Should fix the NPE (I was not sure what security domain config your
example needed in order to reproduce).
The timeout issues should be fixed in Undertow upstream, it looks like
there was two issues:
- The timeout was running in an IO thread
- ThreadLocals where not being properly set up before dispatching to the
error page

Hi,
When using a basic async servlet, where the request processing is
transferred to an @Asynchronous method, there's a NPE at the end of the
request:
Exception in thread "default task-107" java.lang.NullPointerException

The direct cause is that
JASPIAuthenticationMechanism#wasAuthExceptionThrown tries to access the
security context as-in the following line:
SecurityContextAssociation.getSecurityContext().getData().get(AuthException.class.getName())
!= null
Only, for an async request processing thread
SecurityContextAssociation.getSecurityContext() is always null, causing
the NPE. I created a test that functions as a reproducer here:
https://github.com/arjantijms/javaee7-samples/tree/master/jaspic/async-au...
It also looks like there's something not entirely right with the async
time out on Undertow, but I haven't nailed that one down yet.
Kind regards,
Arjan
