As another commenter mentioned, I think this is much more the programmer and less the language. Sure, the language may recommend certain approaches which carry across teams differently, but it still often comes down to the app, not the language. I implemented a rudimentary Java AOT targetting Go and the trimmed-down stdlib grew so big Go took hours compiling it (granted some of that is how I approached OOP and what not).
Yes[0] though I think the issue title is a bit off. They did bring it down from over 7 hours to 30 minutes ish in a recent release, but it's still is too long, too much CPU, and too much mem. They are very reactive of course which is something I can never say about OpenJDK.
