It is possible to trigger a NPE during a failed authentication attempt.
2021-05-07 11:51:57,913 DEBUG [org.jboss.security] (default task-262) PBOX00206: Login failure: javax.security.auth.login.LoginException: java.lang.NullPointerException

This is the following block of code:
if( ((NegTokenTarg)negotiationContext.getResponseMessage()).getNegResult() != NegTokenTarg.REJECTED ) {
log.debug("NegotiationContext.setContinuationRequired(true)");
negotiationContext.setContinuationRequired(true);
}
It may be we have a different message type that should have been available here but if this is a failed authentication anyway detecting null should be sufficient.
