             Summary: Elytron GS2-KRB5 SASL mechanism implementation throws NullPointerException on IBM JDK
                 Key: ELY-1331
                 URL: https://issues.jboss.org/browse/ELY-1331
             Project: WildFly Elytron
          Issue Type: Bug
            Reporter: Josef Cacek
            Assignee: Darran Lofthouse
            Priority: Blocker


The Elytron GS2-KRB5 SASL mechanism doesn't work on IBM JDK.  When GSSAPI is used the call works.

If a user tries to use the GS2-KRB5, then the connection hangs until it times out.

Following NPE comes on the client:
