-----------------------------------------

    Attachment: geronimo-servlet_2.5_fix.zip

I appied this quick and dirty (zip-level) fix, and that is the difference:

> The problem is NOT this exception but in the way it presented.
> This exception is wrapping some runtime or app-specific exception into Servlet exception.
But geronimo is bundled with /org.apache.geronimo.specs/geronimo-servlet_2.5_spec// which
has servlet exception as:
> public class ServletException extends Exception
> {
>     public ServletException()
>     {
>     }
>     public ServletException(String message)
>     {
>         super(message);
>     }
>     public ServletException(String message, Throwable rootCause)
>     {
>         super(message);
>         this.rootCause = rootCause;
>     }
>     public ServletException(Throwable rootCause)
>     {
>         super(rootCause.getLocalizedMessage());
>         this.rootCause = rootCause;
>     }
>     public Throwable getRootCause()
>     {
>         return rootCause;
>     }
>     private Throwable rootCause;
> }
> which of course does not expose class name and stack trace of wrapped exception (I decompile
exactly from /org.apache.geronimo.specs/geronimo-servlet_2.5_spec/1.1-SNAPSHOT/)
> It makes stack trace absolutely unuseful!
> My expectation is that ServletException should be the same as the latest revision in
Tomcat project:
> http://svn.apache.org/viewvc?view=rev&revision=467995
> where the "rootCause" is hadled as "cause" in wrapping constructor of java.lang.Execption.
> I am going to substitute this class in jar manually, to bypass it.
> Of course I understand that this is because of Maven-build-ideology of Geronimo and real
*bug* is in /org.apache.geronimo.specs/geronimo-servlet_2.5_spec/1.1-SNAPSHOT/ artifact. On
the othet hand this is very anoying! Could somebody fix centrally?
