Get the OpenJDK Choose the Build, Test, variant source branches to Deploy Pipeline repo build from

Clone / update from dev if we have OpenJDK AdoptOpenJDK forest changes or or Pull directly from master or Build Test Deploy other variant e.g. if no Available Eclipse OpenJ9 changes

Build via Tests run via Deploy Nightly and / www.adoptopenjdk.net ci.adoptopenjdk.net ci.adoptopenjdk.net or Release builds to .adoptopenjdk.net GitHub

Approved third-party OpenJDK Binaries

@hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams - CI

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