It looks like it's expecting "darwin-x86_64", but now somehow getting "x86_64-darwin".

For comparison this is what I get on Java 8, where it works:

$ jruby -v -w -rffi -e 'p FFI::Platform::ARCH'
jruby 9.1.13.0 (2.3.3) 2017-09-06 8e1c115 Java HotSpot(TM) 64-Bit Server VM 25.122-b04 on 1.8.0_122-ea-b04 +jit [darwin-x86_64]
"x86_64"

It appears to work for me here:

$ jruby -Xnative.verbose -v -rffi -e 'p FFI::Platform::ARCH'
jruby 9.1.13.0 (2.3.3) 2017-10-26 d40ae60 Java HotSpot(TM) 64-Bit Server VM 9+181 on 9+181 +jit [darwin-x86_64]
Successfully loaded native POSIX impl.
"x86_64"

This is Oracle's build of JDK9. What build is that you're running?

This may have been fixed after 9.1.13.

I'm using the Oracle JDK 9.0.1+11 (installed via homebrew cask).

I have reproduced it with JDK 9.0.1 from Oracle. Fix landing shortly.
