Name: PK38005
=============
 
Summary:
   When PPR is enabled, application attributes return null
 
Problem Description:
   With portal 5.1.0.x installed on WAS 6 and parallel portlet rendering (PPR) activated, portlet session attributes are corrupted, e.g. portlets will randomly reveice null attributes for attributes that have been set before or they may overwrite the session attributes of other portlets. This is caused by a behavior change in ServletRequest.getContextPath between WAS 5 and WAS 6 that breaks the PPR session handling
   
 
Problem Solution:
   Backported corrected PPR session handling from portal 6 to portal 5.1
 
Failing Module(s):
   Portlet Container
