[jboss-user] [Security & JAAS/JBoss] - NPE in ExtendedFormAuthenticator

[leegreiner]

I belive I have come across an issue when using the ExtendedFormAuthenticator in 4.0.5.GA. When a user sits on the login page for too long and their session expires the following NullPointerException is thrown in ExtendedFormAuthenticator.authenticate():

13:44:15,765 ERROR [CoyoteAdapter] An exception or error occurred in the container during the request processing
java.lang.NullPointerException
	at org.jboss.web.tomcat.security.ExtendedFormAuthenticator.authenticate(ExtendedFormAuthenticator.java:104)

The session appears to be null and an attempt is made to remove a note from the session thereby causing the NPE. Earlier references to the session are enclosed by if(session != null). The one attempting to remove the note is not.

Any comments?
