Hi Daniel, Chris,
Unfortunately docs are out-dated (I plan to update it in JDK13).
In JDK9
https://bugs.openjdk.java.net/browse/JDK-8041435
changed the behavior - empty address (i.e. only port is specified) means
"local connections only", "*" means "all available connections".
Then in JDK10 new "allow" option was introduced:
https://bugs.openjdk.java.net/browse/JDK-8061228
(it allows to specify list of addresses/subnets to accept connections from).

Hi Arthur,

We have some ipv6 patches as well in this area as well (as well as
other patches to support ipv6 only environments) that we're trying to
upstream. I don't understand the code myself, but it might be useful
to take a look:
http://cr.openjdk.java.net/~aeubanks/jdwpipv6/webrev.00/index.html
SocketTransportService.java:
On my machine at least, InetAddress.getByName("localhost") and
InetAddress.getLocalHost() are quite different:
InetAddress.getByName("localhost") will return the loopback (127.0.0.1)
InetAddress.getLocalHost() returns the local hostname (dhcp-XXX-XXX...)
If I'm not mistaken your changes in HostPort would transform something
that previously returned the loopback (no host specified) with something
that returns the local host name ("*" specified).
So I'm not sure these changes are quite right.
Maybe Alex will be able to confirm.
We need to consult the documentation for the command-line tools that
exercise this code, or the higher-level API spec for the expected
behavior of `*`, port-only specified, etc.
