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!
