could you please post your nrpe.cfg (sanitize as needed) to make sure
there is not a typo in it? (I've had that many times myself, very
frustrating).

Another option worth exploring is
http://search.cpan.org/~roland/jmx4perl-0.65/scripts/check_jmx4perl.

Another thing: I am not sure how nrpe escapes the slashes (if at all)
in the uri in that check. Try adding more on slash in front of every
other slash. Just a wild shot, I know.
