They will eventually submit such patches to the OpenJDK project. At the same time, Oracle reserves the right to rapidly release any critical security patch to their paying customers. Oracle sponsors the OpenJDK project as part of that commitment. Oracle has publicly declared their intent to keep Oracle JDK at feature-parity with OpenJDK. The first and last offer paid support programs. GraalVM - a special product, a Java VM and JDK based on HotSpot/OpenJDK, implemented in Java, and supporting additional programming languages and execution modes, like ahead-of-time compilation of Java applications for fast startup and low memory footprint.Īll three of these are based on OpenJDK source code. - a build of OpenJDK without any fees and without any support.Oracle JDK - their branded product requiring a fee for production use, with paid support available.Oracle is one such vendor, providing three products: Many vendors provide builds/installers based on the OpenJDK source code. I am evaluating Oracle Open JDK and AdoptOpenJDK, and they both seems to be an idea choice.īe clear on this: The OpenJDK project publishes source code only, not builds nor installers. But you did not mention any criteria other than needing security updates rapidly (more on that below). My question is - which distribution of the OpenJDK would be a better choice?Īnswering that depends on the criteria important to you. That product is still free-of-cost for use in development, testing, and such.

So if I switch to Oracle OpenJDK, then I will have to follow the new release cadence to be up to data with security patches (I don't care much about the new features), however If I switch to AdoptOpenJDK, then I can go with one of their LTS version (11), and expect the new security patches will be applied to this version. However when it comes to support, Oracle OpenJDK is following a 6 month release cadence without any Long term support, however AdoptOpenJDK has LTS for Java version 8 and 11. My question is - which distribution of the OpenJDK would be a better choice? I am evaluating Oracle Open JDK and AdoptOpenJDK, and they both seems to be an idea choice.
