  ****************************************************************
  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
