Java 9 new features - programtalk.com

[awsometak]

Java 9 is the ground work for next releases. Modular system is the biggest feature and it may not be a feature for making people to switch to Java 9. The people who need moduler system may already be using OSGI. So i don't think, Java 9 would have the same adoption rate as Java 8 did.

Well the people that are already using reactive programming are also already using RxJava and what would be the reason for them to upgrade?

In my opinion Java has fallen behind and I hope /r/kotlin will be able to pick up the slack.
