           Summary: suspect that http session expiration fails in Tomcat
           Product: Tomcat 5
           Version: 5.0.28
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: ggolden@umich.edu


Running our application we get reports like this in catalina.out:

SEVERE: An exception or error occurred in the container during the request processing
java.util.NoSuchElementException

        at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:118)

Following this, we see evidence that objects bound to http session state are not getting their
automatic 
expiration unbound calls, thus messing up our application.
