Fix: build

Green: https://travis-ci.org/github/rcongiu/Hive-JSON-Serde/builds/764415727

There's a leaking dependency on a JAR that is no longer available in JDK11.

Easier to grok diff as my editor decided to auto-format.

@rcongiu this is ready to go

Not sure how CI is configured, but maybe click some buttons so that it's visible here in PRs when they are submitted?

Thank you!
