AdoptOpenJDK - Making Java free again

AdoptOpenJDK is the leading provider of OpenJDK™ binaries. With over 170 million downloads in the last year, it is successfully used by many enterprises and ready for your production usage of Java™. AdoptOpenJDK provides prebuilt OpenJDK binaries from a fully open source set of build scripts and infrastructure. This talk will cover how we build on over 15 different platforms, execute over 87 million tests and distribute OpenJDK binaries to millions of users. We will also cover how AdoptOpenJDK binaries compare against the Java binaries that you use today. If you’re curious to understand the difference between OpenJDK, Oracle Java, AdoptOpenJDK and all the other distributions, then this is the talk for you!

25. Supported VMs
26. @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.
27. @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.
28. @hendrikEbbers github.com/hendrikebbers @gdams_ github.com/gdams Supported Platforms
29. @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
