Moving to hotspot-dev and porters-dev in case anyone has something to add. compiler-dev is the javac list. :)

Thanks,

Paul

Hi Tiago,

Please see https://openjdk.java.net/contribute/ - I think the reality is that a significant organization would need to commit real engineering time to support this platform for the long haul.  If your organisation is able to do so then you may wish to start the work and then propose a porting project or a JEP as appropriate.

Cheers,
Martijn

Hello,

I'm new to the mailing list, and i just hope this is the right place to bring this up.

Support for SPARC V8 was removed in 2013 (see https://bugs.openjdk.java.net/browse/JDK-8017756). The argument at the time was that SPARC V8 hardware was not used any more (see https://bugs.openjdk.java.net/browse/JDK-8008407).

Well, it turns out that the the space industry has finally caught up, and the new generation of radiation hardened SoCs, at least in Europe, will be based on SPARC V8 (see https://www.gaisler.com/doc/gr740/GR740-OVERVIEW.pdf).

What would be the effort to revive support for SPARC V8? I think this would be a great opportunity to get Java running on rad-hard hardware in low Earth orbit and beyond...

Thanks
Tiago
