Thanks for the quick review, I didn't even think to check 13, though I
did notice the vanguard change wasn't marked as being in Oracle's 11u.

FWIW, I forgot to mention that I ran the tests in
test/java/util/TimeZone/ and the updated TimeZoneTest.java passes on the
patched version and fails on the original. The rest are the same between
the two.
