PM49914: SIP REQUESTS CAN BE IMPROPERLY INIATALIZED BY SUPPLYING A PARAMETER WHICH IS LINKED WITH ANOTHER REQUEST/SESSION

APAR status

• Closed as program error.

Error description

• When using the method
  
  SipServletRequest createRequest(SipSession session,
  SipServletRequest origRequest, Map<String,List<String>>
  headerMap) throws IllegalArgumentException,
  NullPointerException;
  
  it is possible to provide an origRequest parameter which is
  already linked with another request/session, causing the
  request to persist in memory longer than may be desired, which
  can effectively create a memory leak.
  

Local fix

• supply an origRequest parameter which is newly initialized

  The SIP container save references to all linked requests even
  if the application does not have a reference to the request.
  

Problem conclusion

• The SIP container is not holding a reference to all linked
  requests. When the application remove the last reference to
  the request the request object is collected.
