ADDITIONAL SYSTEM INFORMATION :
Debian 10, Java 17 - not very relevant

A DESCRIPTION OF THE PROBLEM :

Please enhance the java.net.http client to work with unix domain sockets introduced in JDK16.
This will enable java apps to talk with http servers over unix domains.
One popular app that uses this pattern is docker daemon.

It would be great if this fix could be made part of JDK 17.

Right now the http client only supports URI's as parameters.
