Microsoft said it relies on Java technologies for some of its own internal systems, applications, and workloads Java also powers some Azure infrastructure. Some may not have been formally backported upstream and signposted in OpenJDK release notes. Microsoft Build of OpenJDK binaries may contain backported fixes and enhancements deemed important to customers and internal users. Microsoft also has collaborated with Java vendor Azul Systems and others to offer Java support. During the past 18 months, the company has contributed more than 50 patches for OpenJDK, covering areas such as MacOS packaging, build and infrastructure, and garbage collection fixes.

Microsoft said its contributions to OpenJDK started as it learned about the process and how to participate in a meaningful way.
Microsoft has seen increasing growth in customer use of Java across the company’s cloud services and development tools. Microsoft said Java is one of the most important programming languages today, as it’s used for everything from critical enterprise applications to hobby robots. Microsoft, with its Java build, surely has Oracle, with its popular Oracle Java Development Kit (JDK) Java releases, in its crosshairs. Microsoft will support Java 8 binaries from Eclipse Adoptium on Azure-managed services offering Java 8 as a target runtime option. OpenJDK binaries for Java 17 are due by the end of this year. docker run -it -rm -name my-running-app my-java-app. usr/src/myapp WORKDIR /usr/src/myapp RUN javac Main.java CMD 'java', 'Main' You can then run and build the Docker image: docker build -t my-java-app. Microsoft pledges to support Java 11 until at least 2024. In your Dockerfile, writing something along the lines of the following will compile and run your project: FROM openjdk:11 COPY. Microsoft’s binaries have passed the Java Technology Compatibility Kit (TCK) for Java 11.Īnnounced April 6, Microsoft Build of OpenJDK is a simple drop-in replacement for any other OpenJDK distribution in the Java ecosystem. OpenJDK is open source, while Oracle JDK contains proprietary pieces, and thus it is licensed under the Oracle binary license.
īuilds for Java 11 are based on OpenJDK source code, following the same build scripts used by the Eclipse Adoptium project, formerly known as AdoptOpenJDK. Microsoft Azure cloud users can try the build via Azure Cloud Shell.

Microsoft also is publishing an early access binary for Java 16, the latest version of standard Java, for Windows on Arm. Known officially as Microsoft Build of OpenJDK, binaries of Java 11 for Windows, Linux, and MacOS are available at . JDK is the Java Development Kit it is the JRE, but with javac (which is what you need to compile Java source code) and other programming tools added. It will continue to require a valid signature. In a move that could mean serious competition for Oracle in the Java space, Microsoft is previewing its own build of OpenJDK, a freely available, long-term support distribution of open source Java. The Oracle JDK: It has always required third party cryptographic providers to be signed by a known certificate.
