Personally, I am currently using the Zulu release of Java 10.0.1 from Azul on macOS High Sierra successfully with IntelliJ 2018.2 to produce Java-backed web apps with Vaadin. I wonder if they might support a macOS release as well, though it is too soon to tell. Meanwhile, IBM donated code for a JVM to the Eclipse Foundation, now housed in the OpenJ9 project. OpenJDK source code, roll-your-own compilation & installation (perhaps not practical for most of us).Zing line of commercial JVMs with special features such as an alternate garbage-collector.Zulu line of free-of-cost JVMs with optional paid support.Oracle releases of the JDK and JRE, with optional paid support.

At this point, at least three sources are based on OpenJDK for macOS: See this 2017-09 announcement and this posting by Mark Reinhold.Īs a result of all this, macOS users of Java have a choice of vendors for a Java implementation. Notably, the periods for free-of-cost public updates is now shortened. This is part of the shift to a new rapid “release train” plan for predictably scheduled versioning of Java and OpenJDK. The company even donated their previously commercial tools, Flight Recorder & Mission Control, to the OpenJDK project.

Oracle has recently announced their intention to bring their Oracle-branded JVM release to feature parity with the OpenJDK project, with virtually the same code base. Apple ceased distribution of their own branded JVM/JDK, relying on Oracle’s branded releases to include a version for macOS. Years ago, Apple joined the OpenJDK project, transferring their formerly proprietary macOS-specific JVM code as free-of-cost open-source.
