The Red Hat build of OpenJDK

An estimated 15 billion devices run Java™ worldwide1. Until January 2019, no one had to pay for access to a current Java Virtual Machine (JVM), but Oracle implemented a significant change to its release cadence and support model. Oracle JDK is no longer free for production workloads and patches, leaving organizations with a choice to either pay Oracle for continued production support and updates for Oracle JDK, adopt OpenJDK and upgrade every six months, or migrate to an alternative OpenJDK implementation.
