You have to install the Java9 support from the Eclipse Marketplace into it. This will change with Oxygen.1a (shipping Oct 11), which will include Java9 support ouf-of-the-box. Hope this helps! Cheers, -Martin > I got some troubles on getting Oxygen.1 ready for Java 9 ... I don't want to run Oxygen.1 on Java 9, but use it on Java 8, to develop a Java 9 application.
