A preliminary list of Oracle JDK 9 Supported Platforms can be found at http://jdk.java.net/9/supported . Last time I checked, Linux on SPARC was not on that list. Please keep in mind that this list is subject to change throughout the release cycle.

Yes, I'm aware of that list.

Well, dealing with changes to unsupported platforms still requires reviewing those changes, shepherding them to the bug & build systems, through toolchain changes, etc. So it's usually preferable if such activity done by platform experts.

If the platform is unsupported, why do the changes need in-depth reviewal. If it breaks and someone complains, you refer them to the list of supported platforms.

In short, if there is one or more Linux distributions interested in creating and maintaining a port of OpenJDK to sparc-linux, I'd suggest creating a dedicated porting Project, in the same manner how PowerPC64 or s390x were added to OpenJDK mainline. I understand that can be a bit confusing, because 'the code is already there' in this case. ;)

Indeed. The code is already there and I just want to help fix it. A process that normally works very easy in most upstream projects. I have sent in patches to many other projects fixing platform support for Linux/sparcv9, but ironically it's Oracle's own project where that isn't easily possible.
