PM23521: PORTLETCONTAINER HOLDS ON TO THE COMPOUNDCLASSLOADER AFTER ADMIN APP.STOPAPPLICATION, WAS PM23131

6.1.0.6 Download: WebSphere Portal and WCM V6.1.0 fix pack 6

APAR status

• Closed as program error.

Error description

• This APAR is to include the backport container based on WAS
  APAR PM23131 into Portal 6.1.
  Original problem:
  When doing hot-code replacement from RAD 7.5 into a
  Portal 6.1 / WAS 6.1 with an incompatible/invalid change,
  the user cannot recover by restarting the application or
  updating the application so that a subsequent compatible/valid
  change fails.
  
  Thread com.ibm.ws.portletcontainer.runtime
  .PortletWebAppInitialization Collaborator continues to run
  after WAS AdminApp.stopApplication.
  
  Thereby the classloader is not released and a valid Hot Code
  Replace (HCR) after an invalid HCR before the stopApplication
  cannot be done. That's why the application needs to be
  uninstalled/reinstalled or server restarted. This slows down
  the development flow.
