Summary:                    find_package(Java) gives warning "regex not
supported" again
Description: 
Java.cmake has a hard-coded regex to parse java version strings, and it did
not expect 'icedtea' to appear in them.

It did seem to expect 'oem' to appear in them, so blindly piggyback on that
to add 'icedtea'.  (Since a character class is used, it would also support
-tie-me-a-code and other anagrams, but fixing that is best done by
the author of that regex if desired.)

See attached patch.

Steps to Reproduce: 
Same as for bug 11676, but on latest ubuntu (12.04) with latest jdk
(openjdk-7-jdk).

Additional Information: 
Exact log:
