Andy,
Java SE 9 has java.lang.Runtime.Version for manipulating the version
strings returned as system properties. It was introduced by JEP 223 --
see http://openjdk.java.net/jeps/223. Best to follow up on verona-dev.

Hello all,
Many Java frameworks and applications require knowledge of the Java version
they are running on. Currently the only way to check the Java version is
by doing:
String javaVersion = System.getProperty("java.specification.version");
This of course returns a String, which is very awkward to work with when it
comes to comparisons. For example, if I want to check if my code is
running at least on Java 8, I have to do the following:
if (Pattern.matches("1\\.[0-7]", javaVersion))
// at java 7 or earlier
else
// at java 8 or later
It would be nice if the JDK had a built-in enum, similar to what is
provided by org.apache.commons [1], so that Java version comparisons are
less awkward.
I'm not familiar with the process is for getting new APIs into the JDK, but
if it is a simple matter of making a pull request I can certainly do so.
Regards, Andy
