=============
 
Summary:
   IllegalStateExceptions in the log with fragment caching enabled
 
Problem Description:
   When fragment caching is enabled, the portal servlet is not
   "reentrant", i.e. if a servlet filter invokes portal, portal returns and the filter invokes portal again, the request still caches some artefacts, amongst them request objects that contain
   WAS-provided wrappers for fragment caching which have exceeded their lifetime. This leads to IllegalStateExceptions upon using the request object..
 
Problem Solution:
   the iAttributesToRemove in Servlet.java needed to also include "com.ibm.wps.model.impl.LocatorMapperMap".
