Review comment:
A further thing to keep in mind - this implementation is mindful of the
JEP-380 work on java as raised here:
https://bz.apache.org/bugzilla/show_bug.cgi?id=64850
In future, JEP-380 will allow UDS on wIndows and unix, and I have made sure
that nothing done here closes the door on future support.
The https://docs.oracle.com/javase/7/docs/api/java/nio/file/Path.html object
is used as the parameter type as it exists in jdks as old as java7+ and it is
used in the constructor of the proposed java.net.UnixDomainSocketAddress.
This should allow seamless JEP-380 support in future, while giving me my UDS
today.
