Supported VMs

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams HotSpot HotSpot is the VM from the OpenJDK community. ▸ It is the most widely used VM today. e.g Oracle’s JDK. ▸ HotSpot is shipped as part of the OpenJDK source code. ▸ It is suitable for all workloads.

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams Eclipse OpenJ9 Eclipse OpenJ9 is an alternative VM to Hotspot ▸ As a separate download, AdoptOpenJDK bundles this VM with OpenJDK class libraries. ▸ For some cloud/container workloads, it’s faster/more efficient.

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams Supported Platforms

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams Sources ▸ All builds are based on OpenJDK ▸ OpenJDK Mercurial repositories are mirrored into AdoptOpenJDK GitHub ▸ No additional functionality (GC, etc.) ▸ Additional build steps like notarisation for macOS

Test

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams Test Suite ▸ AdoptOpenJDK provides the test suite AQA ▸ Open source test suite comprising of tests from the Java Ecosystem ▸ Includes tests contributed by IBM and other large application/framework tests ▸ Can be used to test any OpenJDK build
