SapMachine is a build of the OpenJDK, maintained and supported by SAP. It provides a free and open-source implementation of the Java Platform, Standard Edition (Java SE). Read this nice article if you want to know more about the team behind SapMachine, our development processes, and how it all got started.
SapMachine follows the release cadence of OpenJDK's long-running JDK Project. The project ships a new feature release every six months, update releases every quarter, and a long-term support release every two years. See also SapMachine's Maintenance and Support roadmap.
SAP is member of the OpenJDK Vulnerability Group a secure, private forum in which trusted members of the OpenJDK Community receive reports of vulnerabilities in OpenJDK code bases, review them, collaborate on fixing them, and coordinate the release of such fixes.
Security updates, also known as Critical Patch Updates (CPU), are released every quarter for all active versions of SapMachine. The release is scheduled for the Tuesday closest to the 17th day of January, April, July and October.
- Windows x64
- macOS x64

Yes, long-term support releases of SapMachine are all JCK verified. For short-term releases at least one platform, usually Linux x86 (64bit), is JCK verified. Further information about the process and a complete list of JCK-verified releases can be found on page Certification and Java Compatibility.
All known differences are detailed in this article.
Yes. The SapMachine team is actively contributing to the OpenJDK. Team individuals are holding different project and group related roles, such as Project Lead, Reviewer or Committer. We contribute new features, but also provide bug fixes and are maintainers of the JDK updates projects.
SapMachine debug symbols are available as a separate download archive in the release section (e.g. for SapMachine 18.0.1.1 on Linux-x64 the correct archive would be sapmachine-jdk-18.0.1.1_linux-x64_bin-symbols.tar.gz).
Download the archive matching your architecture, extract it and copy the contents of the bin and lib folder to the same directory in the root directory of your SapMachine installation.
Yes, you can access it with https://sap.github.io/SapMachine/latest/<jdk-number>/<os-name>-<cpu-arch>/[jdk|jre] , for example for SapMachine 21 https://sap.github.io/SapMachine/latest/21/macos-x64/jdk or https://sap.github.io/SapMachine/latest/21/linux-x64/jre.
