Golang infamously tried to not use libc at all and just use the kernel syscalls by itself. I think they now do use some stuff from glibc? Or maybe they only use the libc on OSes where the kernel interface is not stable, like Windows?

Also, I don't know how much of glibc is used by openjdk, but potentially not a lot because the jvm wants to behave the same on all platforms, so they don't want to rely on behaviors of the libc.

WinAPI for kernel32 is to Windows what libc is to POSIX, approximately. It's a lower level API than a language runtime and is more agnostic to language specifics, but is higher level than a kernel syscall interface.

Go now calls through libSystem on macOS and iOS, at least: https://golang.org/doc/go1.11#runtime

Going from memory here, and it's been a little while (< a year), but Go at least uses enough glibc that if you use certain functions it won't statically link on linux by default anymore, so I corroborate your statement :-) I ran into this when working on https://github.com/FreedomBen/findref which is a command-line utility written in Go
