Can't compile due to jmxfetch wanting a very old version of sun tools.

Cloned the repo, ran mvn clean compile assembly:single per the directions and I get the below error.

[ERROR] Failed to execute goal on project jmxfetch: Could not resolve dependencies for project com.datadoghq:jmxfetch:jar:0.22.0: Could not find artifact com.sun:tools:jar:1.4.2 at specified path /Library/Java/JavaVirtualMachines/jdk-9.0.1.jdk/Contents/Home/../lib/tools.jar -> [Help 1]

the tools.jar file simply does not exist as of java 9.
See the heading 'Removed rt.jar and tools.jar' here: https://docs.oracle.com/javase/9/migrate/toc.htm#JSMIG-GUID-A868D0B9-026F-4D46-B979-901834343F9E

Currently only building with JDK8 is supported, but we are looking into supporting newer JDK versions soon :) Note that this should only be a problem when building, not when running.
