We haven’t fully immersed ourselves in Java 10 yet, and Java 11 is here. Java 11 is important for more than just a few reasons. Oracle has revamped its support model and come up with a release train that’ll bring rapid updates, about every 6 months.

They’ve changed the licensing and support model which means if you download the Java 11 Oracle JDK, it will be paid for commercial use.Does that mean that I need to pay for Java from now on?
NO. Not necessarily unless you download the Oracle JDK and use it in production.

Note: IntelliJ IDEA 2018.2.4 Community Edition already has support for Java 11.
