    ****************************************************************
    When a Kerberos token is decoded in a by the JAX-WS
    WS-Security runtime in WebSphere, the principal name may be
    replaced by the realm name.  This my cause a WebSphere subject
    to be created incorrectly.
    This issue appears to occur after migrating from Java 7 to Java
    8.
    

Problem conclusion

  • The WS-Security runtime in WebSphere uses classes provided by
    Java to decode the Kerberos token.  This problem described in
    this APAR originates in these Java classes. These specific
    Java classes are shipped with WebSphere and not with Java.
    
    Java APAR IJ22840 resolves this issue, but it is included in
    WebSphere under PH22517.  For more information about this
    issue, see the resolution for Java APAR IJ22840.
    
    The fix for this APAR is targeted for inclusion in fix packs
    8.5.5.18 and 9.0.5.5.  For more information, see
