The spec currently says to substitute a template var with ([ˆ/]+?).
The ? is a reluctant qualifier so the capturing group terminates as
soon possible. In your example above there's no reluctant qualifier so
FGH would equal "123fg/jij/abc/de456". You could make it reluctant by
specifying {FGH:.*?} and then FGH would equal "123".
For just @Path("/abc/de{FGH}fg/hij"} we would continue to substitute
the default ([ˆ/]+?) which limits the capturing group to a single path
segment.
