APAR status
Closed as program error.

Error description
May get 500 ERROR, NULLPOINTEREXCEPTION when application is
calling include(req,res).
The webcontainer is setting an object to null in a re-usable
object. Subsequent requests which get the re-usable object then
suffer the NPE until such time as the object is re-set in the
re-usable object.
The relevant call stack for the application include() problem
is:

* RECOMMENDATION:                                              *
****************************************************************
When processing a forward or an include request, in the event
of an unexpected exception the webcontainer attempts to clean
up the request thread before returning. However is does not
track the work done in processing up to the point of the
exception and as a result may attempt to clean up work which
has not been done. This leads to further unexpected exceptions.
Problem conclusion
Forward and include processing has been updated to track work
completed. In the event of an unexpected exception the
webcontainer only cleans up work which was completed prior to
the exception.
