The PowerPC/AIX porting project currently driven by IBM and SAP is a good example how the OpenJDK fosters the cooperation of different players in the Java ecosystem in an open environment. At last years' FOSDEM, we presented our JCK-certified JDK7 port. This year, we will showcase our JDK8 port. But more importantly, we will describe the lengthy process of integrating the port into the main OpenJDK repository, thus making it a first class citizen in the OpenJDK environment.

At last years FOSDEM, we presented our JCK-certified JDK7 port. This year, we will showcase our JDK8 port. But more importantly, we will describe the lengthy process of integrating the port into the main OpenJDK repository, thus making it a first class citizen in the OpenJDK environment. This process includes the creation of a JDK Enhancement Proposals, the agreement on a detailed Integration Plan between all parties, the thorough review of all changes by OpenJDK reviewers, the integration into the main development repositories and finally the downport into a released version.

Of course we will also highlight the general improvements in the OpenJDK code base which are the result of our port. Finally, we will be happy to answer any kind of technical questions regarding a JDK port to a new CPU and OS platform.

The PowerPC/AIX porting project currently driven by IBM and SAP is a good example how the OpenJDK fosters the cooperation of different players in the Java ecosystem in an open environment.

The project was initially started in June 2012 with the goal to provide a full-featured and certifiable version of OpenJDK on the Linux and AIX PowerPC platforms. By now the PowerPC/AIX port can successfully run a couple of different standard benchmarks in mixed mode (C++ interpreter plus C2 "server" JIT compiler) and passes the JCK test on both platforms.

This talk will describe what we've done to reach the current state and what still needs to be done until we can integrate our port into the main JDK8 code line which is the ultimate goal of the project.
