Reminder: Tests should not be listening on public IP addresses

[Mark Thomas <ma...@apache.org>]

Hi all,

After a recent round of Java security announcements this is just a
reminder that tests should not be opening sockets and listening for
connections on public IP addresses.

If you need to start a server as part of a test, please ensure that the
server socket is bound to the local loopback address.

While it was Java that triggered this reminder, it applies equally to
all projects using the ASF CI services.

Thanks,

Mark
