REPORT #739 Details.

Project: Tomcat
Category: Bug Report
SubCategory: New Bug Report
Class: swbug
State: received
Priority: high
Severity: critical
Confidence: public
Environment: 
   Release: 3.2.1
   JVM Release: java version "1.3.0_01" Java(TM) 2 Runtime Environment, Standard 
Edition (build 1.3.0_01) Java HotSpot(TM) Client VM (build 1.3.0_01, mixed mode)
   Operating System: Windows 95
   OS Release: 4.00.095 B
   Platform: x86

Synopsis: 
Problem when I try to store a referance to the session in the context and then when I 
try to access it in the next request I get NullPointerException

Description:
The same code works just fine on tomcat 3.1.1.

The problem to me appears to be due the fact that I save a referance to the 
HttpSessionFacade ( HttpSession to the servlet) in the ServletContext.
In the next request when I try to access this object after retrieving it from the 
context, tomcat has already called the method recycle() on the facade object and the 
HttpSession reference inside the class HttpSessionFacade is null and I end up with 
NullPointerException.
