Oracle intends to provide full, paid support until 2026 or later. It cannot be used in production without paying Oracle (so it's a trap for the unsuspecting). It can be downloaded and used free of charge for development use only. This is a commercial version of the brand with paid support. This is the main distributor of Java 11 (already released). ![]() ![]() Without further ado, check out the following JDKs that are ready to download: Oracle JDK In short, the OpenJDK + Vendor process transforms a source base into several different builds. For example, AdoptOpenJDK builds that pass the TCK are not "Java SE," but "Java SE compatible" Also, note that certification is currently on a trust basis - results are not sent to JCP/Oracle for verification and cannot be made public. Note that the build cannot be called "Java SE" without the vendor obtaining a commercial license from Oracle. If an organization produces an OpenJDK build that complies with the entirely TCK, this build may be described as "compatible with Java SE". Certification is performed by the Java Community Process (JCP), which provides a Technology Compatibility Kit (TCK). However, there is a separate certification process that must be used to ensure that construction is valid. Anyone can pick up this source code, produce a build, and post it to a URL. In practical terms, there is only one set of source code for the JDK. However, along with this news, how are JDK builds available? Will they be free or paid? Before answering this, it's important to understand what a "valid" JDK for distribution actually means. The community made up of the Java Champions also spoke about it, explaining the changes in detail here. In addition, it has changed the way support for the versions will be offered, providing only support for LTS versions. I don't think they change anything in the JDK but just create custom delivery tools around it.Recently (or not so much), Oracle announced that it will change the way Java evolves, adopting the "Release Train" to launch new versions. My guess is that the company is just using OpenJDK to give better service to its subscribers so they will get notified when new fixes and patches become available to the general public. If you read here you will see that Zulu too is just OpenJDK certified and promised to be maintained. You might opt to just branch the OpenJDK to make your own version.Īt the moment Oracle is going to stop giving its own implementation of the JDK for free but it its version of OpenJDK will remain open and free. But it could be rejected or the time it takes for it to be approved takes too long. You then can try to improve it and submit it to be part of the Oracle OpenJDK. The main reason for creating them was to tweak some parts of the code to better handle a part of the API that you think should work differently.įor example, let's say you are a company that uses JAVA and notices that some part of the API works to slowly for your needs. The official Open JDK and Oracle's JDK are based on the same code but have different licensing models. ![]() Hopefully, we will see more companies paying for support for the products they rely on to help make money, but also see a variety of options for free use in a secure way. ![]() The OpenJDK has been around since Java 6, but there were some differences and not a strong reason for many to shift versions.įrom Java 11, the main difference between OpenJDK and Oracle Java 11 is the installer. Is this because Oracle made the JDK commercial? Other organisations such as AdoptJDK and RedHat have their own releases. To get Oracle's supported releases you need to pay a subscription. However, there are other organisations, like Azul, which provide commercially supported releases from Java 8. Oracle will provide free support for the latest version for the first 6 months of release. You can download the last free version from Oracle.įrom March 2019, Oracle will only give free support for Java 12 (for 6 months). In short, there is no version of Java 9 freely supported by Oracle. Why do people use Azul’s Zulu 9.0.0.15 release of OpenJDK instead of JDK downloaded from ?
