I'd say extend UriBuilder with a match() method instead of adding yet
another class we have to include within RuntimeDelegate. Something like:
Map<String, String> match(String URI);
match() returns null if it can't match the current expression with the
passed in URI.
Useful. Yes. Include in JAX-RS 2.0? Well... I don't get it...you've
deferred some pretty trivial improvements that I've submitted and in
some cases important JIRAs like:
JAX_RS_SPEC-339
JAX_RS_SPEC-317
But you want to include a brand new feature? Plus complain everytime I
make a suggestion that we're too close to the PFD? A bit hypocritical
don't you think?
