RFR 8159487: Add JAVA_VERSION, OS_NAME, OS_ARCH properties in release file

[Sundararajan Athijegannathan]

Please review http://cr.openjdk.java.net/~sundar/8159487/webrev.00/ for
https://bugs.openjdk.java.net/browse/JDK-8159487

OS_NAME, OS_ARCH, OS_VERSION properties are already added due to another
fix. Just adding "JAVA_VERSION" and a test change to check these
properties exist in release file.

Thanks
