Darn, that's unfortunate (and it didn't click initially, because a lot of
the other builds are based on Java 7).
A better interim solution would be to downgrade the library (but still
upgrade against the original code) to version 4.5.0, before the restriction of
Java > 7 was introduced. This is the first major version to allow for post
commit hooks, which is the point of this PR.
I've edited my branch and [launched a build on
Travis](https://travis-ci.org/kokes/zeppelin/builds/310033105). Let's see how
that one goes.
