Subject: [PATCH] Update metrics to support java 9

http://openjdk.java.net/jeps/223
Java decided to change their versioning scheme and in doing so modified the
java.version system property to return $major[.$minor][.$secuity][-ea], as
opposed to 1.$major.0_$identifier we can handle pre-9 by checking if the "major"
is equal to "1", otherwise, 9+

of course, it really wouldn't be all that simple if they didn't add a quirk, now would it.
valid strings for the major may potentially include values such as -ea to deannotate a pre release
