Subject: [PATCH 1/2] bump checkstyle version to build on Java 9
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The version of checkstyle we currently use uses tools.jar
which is removed from Java 9 and above as part of Project Jigsaw.
This commit uses a newer version of checkstyle that does not
use tools.jar.

Running `mvn checkstyle:checkstyle` succeeded.
