Version 16 of the Java Development Kit (JDK) is now in the Second Release Candidate Phase (RC2) and on track for an early March release. Mark Reinhold, chief architect of Oracle's Java Platform Group, announced the Java SE Platform reference implementation's status on the JDK mailing list.

Java 16 is not a long-term support (LTS) release, so it will become obsolete in September, when the next LTS release is due.
