Java, as developed by the OpenJDK Project, owned and primarily employed by Oracle, has been on a 6-month rapid-release cycle since the release of Java 10. Starting with Java 11, had new LTS releases every six releases (three years), followed by Java 17, after which the LTS frequency will be increased to every four releases (2 years).

Java 8 is the last release on the old cycle methodology still in active support. Non-LTS releases are supported for 6 months. The latest supported release in each release cycle can be found at https://www.oracle.com/java/technologies/java-se-glance.html.

Official builds and support from Oracle come in two varieties: open source under the GNU GPL, and a proprietary license that must be purchased. Only the very latest Java release is available pre-built with the open source license, one must purchase support to get builds from Oracle for 8 or 11. Other projects such as Adoptium or Linux distributions may provide builds external of Oracle and are governed under the open source license.
