All platforms are affected, but it is only problematic in environments in which `os::free_memory()` is slow. That was reported for some kind of container environment on linux x64. I think we should have this fix in 17u because JDK 17u is probably used in such environments, too. I think the risk is low, but we could also ship it one release later.
