APAR status

  • Closed as program error.

Error description

  • After calling the changeSessionId() method, a difference in
    behavior may be seen between enabling and disabling session
    replication.
    
    When session replication is enabled, the session may not be
    found on subsequent requests.  This can result in a new session
    being created.
