I managed to simplify the script down to a one-liner - giving the same
version as Edourard's:
(display (run-with-store (open-connection) (package-file icedtea-8 #:output
"jdk")))

Bjoern was correct that this was not the version I was looking for - but
having rethought my dependency issue - I managed to solve it a different
way using substitute* to patch the relevent files at build-time.

Still, I learnt quite a bit about the gexps, the store, and patching - so
time well spent - thanks again :-)
