PM21203: PORTLET LOAD MONITORING DOES NOT REDUCE THREAD COUNTER IF PORTLE T THROWS AN EXCEPTION

APAR status

• Closed as program error.

Error description

• Portlet Load Monitoring does not reduce the request counter if a
  portlet request ends because the portlet throws an exception. In
  consequence the request counter is not correct and Portlet Load
  Monitoring may erroneously block portlets.
  As another issue, Portlet Load Monitoring may block a portlet
  request (e.g. a render request) even when a preceding portlet
  request (e.g. action request) during the same client request
  ended successfully without being blocked.
  

Local fix

Problem summary

• Portlet Load Monitoring does not reduce the request
  counter if a portlet request ends because the portlet
  throws an exception. In consequence the request counter
  is not correct and Portlet Load Monitoring may
  erroneously block portlets. As another issue, Portlet
  Load Monitoring may block a portlet request (e.g. a
  render request) even when a preceding portlet request
  (e.g. action request) during the same client request
  ended successfully without being blocked.
  

Problem conclusion

• Portlet Load Monitoring is changed to reduce the request
  counter if a portlet throws an exception.
  In addition Portlet Load Monitoring notices if a portlet request
  ends successfully (i.e. without being blocked) and does not
  block subsequent portlet requests during the same client
  request.
