    * PROBLEM DESCRIPTION: An LDAP request time out is leading     *
    *                      to a NullPointerException.              *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When attempting to make a connection to an LDAP server a
    connection timeout was leading to a NullPointerException when
    trying to release the DirContext object. Since the connection
    was never made due to the timeout, the DirContext instance was
    null leading to a a NullPointerExceptoin.
    

Problem conclusion

  • The DirContext is now checked to ensure it is not null before
    trying to release it.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.45, 8.0.0.14, 8.5.5.12 and 9.0.0.5.  Please
