The Java language and runtime are critical technologies that power businesses, governments, and open source infrastructure today, and by all accounts will continue to do so well into the future.

Software development is in the midst of a sea change with innovation in continuous delivery and deployment, serverless architecture becoming a new normal, and applications driven by data and AI. All of these changes have ignited the Java community to set a rapid pace for innovation within its own ecosystem, adopting a six-month rapid release cadence for Java features and the adoption of OpenJDK.
