Error caused by

jruby/core/src/main/java/org/jruby/ext/socket/Addrinfo.java

Line 786 in a5bf7de

private Protocol protocol = Protocol.getProtocolByNumber(0); 

private Protocol protocol = Protocol.getProtocolByNumber(0);

Because getprotobyname_r not exists in musl lib.

This is a jnr-netdb fix. We'll leave this open until we upgrade to a fixed version.

It was message from library and that library continued to work.
I moved to alpine with glibc and that message is gone

We'd still like to be able to support musl libc even though it has some rather different functions than glibc. Is this still a problem on musl with current JRuby?

@headius I just encountered the same error on jruby 9.1.12.0 on a musl Alpine.

Working fine with glibc on alpine, I'm using this image https://hub.docker.com/r/anapsix/alpine-java/
