On macOS Sierra, it takes several seconds to resolve the local hostname

[big-guy]

Other Java tools are experiencing a problem with looking up the local hostname on macOS Sierra (10.12). Here's a longer description of the problem: https://thoeni.io/post/macos-sierra-java/

Expected Behavior

Local host look-up should be speedy, or if not, cached.

Current Behavior

I suspect this causing a problem here:
https://discuss.gradle.org/t/gradle-always-execute-creating-new-in-memory-cache-for-repo-maven-when-i-build-project-i-configurated-org-gralde-daemon-true-in-gradle-properties-the-command-line-properties-like-org-gradle-daemon-true-are-ignored/20080

Context

We have an uncached hostname look-up here:
https://github.com/gradle/gradle/blob/master/subprojects/resources-http/src/main/java/org/gradle/internal/resource/transport/http/ntlm/NTLMCredentials.java#L64

We have a cache in InetAddressFactory for this look-up that we could re-use. This has a large impact on builds with many repositories.

Steps to Reproduce (for bugs)

This happens always.

Your Environment

macOS Sierra

It seems to be an issue in the JDK actually, calling an inefficient native method: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8170910

I guess we could work around this by implementing our own logic in native-platform. We should also push for a solution to this issue.
