What is the primary development platform for OpenJDK HotSpot JVM?

[Alex Yursha]

Sorry for ambiguity. My question was about the current state of affairs.

So does every HotSpot developer assumed to be an expert in all supported platforms or are there experts in specific platforms who assist in porting?

I also wonder if there is a platform which is used much more often for feature prototyping or is the work distributed almost equally between Solaris, Linux and Windows?

Thanks

Or do you mean currently are new features developed on one platform and then ported to the others? For this latter question typically new features are prototyped on the platform most accessible to the developer doing the work, but quickly ported to the other platforms - often only becoming visible to others once all platforms are supported.
