Hi Arthur,

Not directly related to Alex's original question but...

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.

best regards,
