> If you try to use Daffodil with Java 10, you get a failure with the exception:

> It looks like Java changed their version schema to not use a dot (e.g. 10 vs 1.10) and Scala 2.11's checker could handle that, so a NumberFormatException is thrown.
> It looks like scala 2.12 has better checking for this (see DAFFODIL-1652), but we should also catch a NumberFormatException here and treat that as if it is not a valid Java version.
> This was reported on Java 10, but I suspect the same issues happens for Java 9. Also, we should run our tests on Java 9/10 to ensure tests still pass with a newer Java.
