cheers for the history Alan.
I wasn't sure if 9-ea was going to be used purely during early access or if a new structure was going to be used.
is their a source file, java doc or mail list message detailing the changes or new Java 9 setup. So I can reference that in any potential change I submit to open source projects?
looking at the submitted patch, am I right to assume java.version going forward will be the purely a display string value and java.specification.version should be used to work out the major version number. Should I also assume their will be a java.implementation.version if you need to know the low level build number.
Not sure if that patch fixes all the issue I'm seeing or not. I'll play around with it when I've next got a sleeping baby on my shoulder and see if I get any further.

> In a recent mail to jigsaw-dev , Robert Scholte mentioned that the new version-string scheme may be problematic for some Maven plugins. He mentions the plexus-archiver specifically and that seems to have a patch already. If the maven-javadoc-plugin needs updates too then it's best to get a bug submitted so that it's on someone's radar.
