Java 9 should be fully released for general availability on 21 September 2017, after chief architect at the Java Platform Group, Mark Reinhold announced delays to the rollout citing “additional time required to move through the JCP process” being the cause.

This delay comes after a variety of previous setbacks, mainly due to issues with its modularisation effort that was already left out of Java 8, which was released three years ago, making modular Java a feature in Java 9 instead.

Oracle has offered early availability for those wanting to download and test the new platform. If you’re interested, new updates are being published daily for
testing.
