Java Development Kit 22, set to arrive in March 2024 as the next version of Java Standard Edition, has grown to include eight features so far, with a preview of a class-file API, region pinning for the G1 garbage collector, and a second preview of implicitly declared classes and instance methods proposed in the past few days.
A possible ninth feature, stream gatherers, has been tentatively designated for JDK 22 but was not listed yet on the official JDK 22 OpenJDK web page as of November 20.
