I don't understand URLs.
(English)-1.2.jar

A quick X-ray operation with xr.el, suggested to me that the parenthesis
- () - around English could be the problem maker. So I removed the ()
around English and re-builder matches the whole url.
Here is what xr.el reports.
xr.el is at

As an aside,
If I do,
M-x browse-url-emacs RET
with point on that link, I am prompted for the "whole" URL. The
interactive spec for browse-url goes something like
(interactive (browse-url-interactive-arg "URL: "))
which in turn relies on
(thing-at-point 'url t)
So may be Gnus, can fuzzily position itself on what looks like a URL and
then defer to `thing-at-point' to do the nasty work of identifying the
boundaries. This way, atleast Gnus owners can blame someone else :-).
