JDK 9 ea 99 java.version

[John Patrick]

evening,

Does anyone know how to override the java.version field?

Wanting to help out with getting JDK 9 ready, using it and building
projects with it.

Most patches I've submitted so far as simply bumping which is the min java
version being used from 1.5 to 1.6.

One issue that I can't figure a work around for java.version. I'm getting
the following error from maven-javadoc-plugin.

[WARNING] Unable to find the javadoc version: Unrecognized version of
Javadoc: 'java version "9-ea"

[WARNING] Using the Java the version instead of, i.e. 0.0
[WARNING] -quiet option is not supported on Java version < 1.4. Ignore this

My question is should maven and every other project accept 9-ea as a valid
java.version string, or could build 100 plus tweak the java.version string
to something else that is considered valid.

Cheers,
John
