TIP: link:https://openjdk.java.net/jeps/12[JEP 12] provides for a preview language or VM feature, which "is a new feature of the Java SE Platform that is fully specified, fully implemented, and yet impermanent. It is available in a JDK feature release to provoke developer feedback based on real world use; this may lead to it becoming permanent in a future Java SE Platform".
