The goal of this project is to provide a full-featured and certifiable Linux/s390x port of OpenJDK in the main OpenJDK development branch.
Ongoing work
SAP is continuously building and testing the port in the jdk11u codeline to avoid any regressions.
Further SAP is maintaining the port in jdk/jdk and new releases together with IBM.
