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
