APAR status

• Closed as program error.

Error description

• HTTP session cannot be stored into a session database due to
  the exception: NotSerializableException. This occurs because
  the object implementation javax.faces.application.FacesMessage
  is not serializable.
  
  This seems to occur when JSF flash mode is set to keep messages
  (setKeepMessages(true)). This is required when
  POST-Redirect-GET-principle is in use to avoid the loss of
  faces messages. If the "keep messages" parameter is set to
  false, the user will not see the messages.
  This can be reproduced by selecting the option to "store all
  attributes of the HTTP session" option in WebSphere
  Application Server's session persistence configuration.

  ****************************************************************
  The javax.faces.application.FacesMessage implements the
  java.io.Serializable interface, but its inner class Severity
  is not serializable.
  An exception similar to the following can be observed in the
  log:
  javax.faces.FacesException: java.io.NotSerializableException:

Problem conclusion

• The JSF MyFaces code was updated to properly implement
  serialization of the FacesMessage object.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.11 and 8.5.5.6. Please refer to the
