We don't want to have code that hasn't been reviewed enter the mainline JDK.

I think the issue where semantics clash is what constitutes fixing a 
port. From my perspective, that entails not just getting OpenJDK to 
build on a given platform, but also making it work well, and creating a 
sustainable effort around it to maintain it, so that it doesn't bit rot 
over time.

The Linux SPARC port seems to have received occasional bursts of 
activity (mostly from Oracle, afaict) that take care of the first two 
items, which is fine and well. Unfortunately, no specific long term 
effort seems to have formed around the port it to maintain it across the 
Linux distributions, and that's the kind of problem where one-off build 
fixes are just a small piece of the puzzle.

Of course, forming a Project to maintain a port is not a panacea, 
either. But it provides a structure within which developers interested 
in a port can chose to collaborate (or not, this is open source, after 
all, and eternal balkanization of effort is its cute curse ;).
