Oracle Code One 2018 Keynote Java is still free.

*** 2018/10/10 postscript ***

Java is still available for free as of October 10, 2018. For more information, see Java is still free Created by Java Champions.

Here's a pretty brief explanation of how the Oracle JDK has changed. Until Java 10, Oracle added a few features to the source called OpenJDK to create binaries and distributed them for a fee or for free. From Java 11, we will pass the slightly added functionality to OpenJDK (some of which is Jakarta EE, etc.). However, the way of thinking has changed to the way that binaries are distributed only for a fee [^ 1].

By the way, organizations and companies other than Oracle also provide binaries, so if you use Java SE 11 or later, it will be the same as before. In particular, the free binary recommended by JJUG etc. is AdoptOpenJDK [^ 2]. It has the longest support period and is supported for 4 years.

Other Amazon Linux 2 also released Java8, Java11 2023/6 / It seems to support up to 30.

New release model and license offer for the JDK

About the new release model and license provided by JDK

Excerpt

● Regular release cycle 6 times a year In addition to the feature release once every 6 months (March and September every year) when new features are added, the update release with vulnerability countermeasures is released 4 times a year (January and April every year). July, October) We will provide it.

● Applying the GPL v2.0 license To facilitate the distribution of the free version, the OpenJDK binary built by Oracle will be distributed as an official binary under the open source license "GNU General Public License (GPL) v2.0". However, user-developed applications are exempt from GPL v2.0 by a GNU Classpath Exception.

● Free paid features of Oracle JDK We will publish the functions of Oracle JDK that were provided for a fee in OpenJDK. These features will be available free of charge in the future (all will be available from JDK 11).

● When to end the free update and provide paid support The official OpenJDK binaries built by Oracle will finish updating the old version when the new version is released. Users of the free version can continue to update the JDK for free by migrating to the new version. For users who want to continue updating the JDK with a specific version, we will provide the Oracle JDK binaries for a fee for feature releases specified by LTS every three years from JDK 11.

About Oracle's new licensing system

About older versions of Oracle JDK 10/9/8/7/6/5 etc.

The version that was provided free of charge during the official update period so far will continue to be available after September 2018. If you wish to obtain the update of the relevant version even after the official update is completed, you need to purchase a Java SE paid license and conclude a support contract.

[^ 1]: From Java 11 there is a free license called OTNLA for Oracle Java SE. See here for details "JDK: New Release Model Description"

[^ 2]: Only Oracle will release the Oracle JDK immediately after the launch of the Open JDK, but for AdoptOpenJDK etc., the binaries will be distributed with a delay of about a week or two because the binaries are verified after the launch. The point is, don't worry if the binary creation is delayed.
