SAP’s Engagement in the OpenJDK project

While SAP maintains SapMachine as a downstream fork of the OpenJDK project to provide a binary distribution tailored to the needs of SAP customers and partners, SAP engages notably in the OpenJDK project itself and generally works on SapMachine in an OpenJDK-first model.
