    > http://www.foo.com/getsource.jsp/

    > The later URL will deliver the jsp source to the browser.

    > I reported this problem to IBM approximately 9 or 10 months ago.

    > Since I reported this "non-security" bug so long ago I hope it is fixed

    > As far as I know this vulnerability was not yet reported to the public.
