Support of additional features & tools (Web-start, IntelliJ IDEA, Java FX, etc.).We’ve assessed all JDK builds using the following criteria: Here is the full list of JDK builds we’ve researched: The most popular and famous builds are distributed by Red Hat, Azul and community-led Adopt OpenJDK. If an organization produces an OpenJDK build that passes the TCK then that build can be described as “Java SE compatible”. This certification is run by the Java Community Process, which provides a Technology Compatibility Kit (TCK or JCK as Java). So, Oracle created a certification process that should be used to ensure the build is valid. It is hosted in Mercurial at OpenJDK.Īnyone can take the source code, produce a build, and post it.

Most of them have different support models (free and paid for), and different attitudes toward providing updates for multiple Java versions.Īs Oracle is not the only vendor in this game, it’s time to look beyond their JDK.ĭevexperts is happy to share with you the results of our research.īasically, there is only one set of source code for the JDK. The changes to the Oracle licenses forced us to look for other JDK vendors. The up to date prices on the Oracle Java SE Subscription can be found here.

Oracle Open JDK (open source), which can be used in any environment for free.

Oracle JDK (commercial), which can be used in development and testing for free, but you have pay to use it in production.

Instead of a single JDK build available both for commercial and free users, they offered two different JDK builds: Then, in 2018, Oracle changed the license of their JDK. In the past, many of us have simply downloaded Oracle JDK and used it in development, testing and production. This means that Oracle will continue to provide free public updates and auto updates of Java SE 8, until January 2019 for commercial users and at least until December 2020 for personal users. If you stay up to date on news from the Java community, you have heard that Oracle has changed their support model for Java.Īccording to Oracle website, Java SE 8 is going through the End of Public Updates process for legacy releases.
