Problem summary

  • ****************************************************************
    * USERS AFFECTED:  IBM WebSphere Application Server            *
    *                  Traditional and Liberty users of WebSockets *
    *                  and SSL                                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: A NullPointerException FFDC can be      *
    *                      generated while utilizing WebSockets    *
    *                      and SSL.                                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    WebSocket connections will cancel outstanding reads for various
    reasons, such as closing the connection. When this happens with
    SSL enabled, the SSL Channel could throw a NullPointerException
    and an FFDC would be generated.
    

Problem conclusion

  • The SSL Channel was modified to use the previously set callback
    to avoid the NullPointerException.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.3, 8.0.0.15, 8.5.5.13, 9.0.0.6.  Please refer to the
