You cannot bind to a port that's already in use.

But if you're trying to connect to a port in the ephemeral range that's
not in use, and the OS happens to assign that same IP:port to the local
socket, it can connect to itself.

(We've run into this in JGroups before, and it was a pain to track down
what was going on).
