    ****************************************************************
    Encountered an SSL Exception when enabling SP800-131
    with TLSv1.3 protocol. This happened after a JDK8 upgrade to
    SR8FP5.
    

Problem conclusion

  • To prevent SSL Exception caused by using TLSv1.3 protocol
    with SP800-131, fixed the code to use only TLSv1.2 protocol if
    SP800-131 is enabled.
    
    The fix for this APAR is targeted for inclusion in fix pack
    8.5.5.27 and 9.0.5.22. For more information, see 'Recommended
