The goal of this project is to provide a full-featured and certifiable Linux/s390x port of OpenJDK in the main OpenJDK development branch.
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.
Contributions to the port are always welcome. We maintain some issues in the OpenJDK Jira, feel free to address any of these:
In 2018, JDK 10 and JDK 11 have been released for linuxs390x. Since JDK 11 Class Data Sharing and Java Flight Recorder are supported. Many issues have been fixed.
In 2017 JDK 9 has been released for linuxs390x.
In November 2016 the port has been integrated into the jdk9/hs repository. It passes the jtreg and jck test suites in a similar scope as other platforms.
