Error description
The JSP container did not detect an update of the new JSP sent
by request#1.  When request#2 arrived, it did not indicate a
reload is needed, that's why the old image is serverd. This
problem ONLY happened when request#2 arrived during request#1 is
compiling the new JSP.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All users whose applications send two or     *
*                 more requests to the same JSP as the JSP is  *
*                 recompiling                                  *
****************************************************************
* PROBLEM DESCRIPTION: After a JSP is modified, first request  *
*                      triggered a re-compiliation of the      *
*                      JSP. During the re-compilation, a       *
*                      second request sent to the same JSP     *
*                      received a response composed from the   *
*                      older version of the JSP.               *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The JSP container failed to detect that a new version of the
JSP is being re-compiled. Instead of reloading the new version,
the JSP container sent back the cached content which contained
the older version of the JSP.
Problem conclusion
New code is added to the JSP container code to detect this
condition.  Once a newer version of JSP is detected, the
container will refresh the cahced copy. As a result, the
new JSP will be sent back for the second request.
