I assume many of you already heard that
Java 9 is scheduled
for GA on July 27, 2017. The Planning
Council did not yet decided how we will ship the Java 9 support for Eclipse
but requires all release train projects to assess their readiness regarding
Java 9. We have created the following wiki page to capture this: https://wiki.eclipse.org/Java_9_Readiness.
That wiki page also explains how you can check your project and how you
can launch Eclipse with a Java 9 VM.
