RequestDispatcherImpl does not set root cause exception

           Summary: RequestDispatcherImpl does not set root cause exception
           Product: Tomcat 3
           Version: 3.2.1 Final
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Servlet
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: jarekk@axit.pl


When a forwarded servlet throws an exception other than ServletException or 
IOException, the thrown exception is lost. This is due to the line:

throw new ServletException(sm.getString("dispatcher.forwardException", t));
(found in org/apache/tomcat/facade/RequestDispatcherImpl.java:210)

the earlier catched t is here not passed into the constructor of 
ServletException but into getString.

To reproduce construct a servlet that throws an Exception (other than 
ServletException and IOException) and another servlet that forwards to it. You 
will get just a forwardException (if you have the proper locale strings 
installed!) but the originally thrown exception will get lost forever.

We use a local patch that replaces the above line with:

Tomcat 3.2.3 does NOT fix this problem
