             Summary: NPE in server log if client's password is null 
                 Key: WFLY-7969
                 URL: https://issues.jboss.org/browse/WFLY-7969
             Project: WildFly
          Issue Type: Bug

            Reporter: Josef Cacek
            Assignee: Darran Lofthouse
            Priority: Blocker


If standalone JMS client creates connection with username and password where password is {{null}} like:
{code}
connectionFactory.createConnection("admin", null);
{code}

then server logs NPE:
