Java 24 / JDK 24: General Availability

[Mark Reinhold]

JDK 24, the reference implementation of Java 24, is now Generally
Available.  We shipped build 36 as the initial Release Candidate of
JDK 24 on 6 February, and no P1 bugs have been reported since then.
Build 36 is therefore now the GA build, ready for production use.

GPL-licensed OpenJDK builds from Oracle are available here:

  https://jdk.java.net/24

Builds from other vendors will no doubt be available soon.
