           Summary: PageContext pool not resetting pages fully before
                    returning to pool
           Product: Tomcat 5
           Version: Unknown
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Jasper
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: [EMAIL PROTECTED]


I couldn't find a bugzilla for tomcat/jasper 6 so I'm posting this
here instead.

I found a bug whereby the BeanELResolver maps and caches classnames
to class instances, which in and of itself is fine, but the PageContextImpl
class also uses a pool for PageContexts, and the whole resolver hierarchy
wasn't being cleaned out when a PageContext is put back in the pool.
The reported symptom was ClassCast exceptions after a webapp was stopped
and restarted and an expression using a class from the webapp was
evaluated.

Attached is the simple test case and the patch file. Actually, looks like I
can't attach anything. I'll try putting it in as another comment.
