MC-4010Unable to stop server when it fails to bind port
Sometimes I have few servers running on my PC (which are played on via LAN). Today I was purging my HDD and deleting old servers (I have many directories with servers and their configs and maps). Many of them had port 25565 (the default one) set in server.properties file. And I had already one server running on that port (and there were 3 players there so I couldn't stop it). So several times I got the FAILED TO BIND PORT message. Then every time I wrote "stop" in the terminal with the screen attached under which the server was running. And no time I succeeded. The server is unable to stop itself after getting command "stop" when it's unable to bind port. But when is receives SIGTERM signal, it terminates correctly. Here is the server log:

There you can see that I started the server, then it failed to bind port and I was writing stop, which didn't do anything. Then, in 19:02:06 I opened htop and terminated it via signal.
I was angry and repeating the command, as you can see. It's not pleasure when this happens many times to me. I had to detach screen every time and start htop, then terminate the server and exit htop. If the bug was fixed I would only have to just write "stop" when this happens. Please, fix this issue. I hope it doesn't depend on some server core mechanics, and it is only one forgotten if() to check something's status or something.

No answer on querry, assuming not an issue anymore.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

If it failed to bind port, just use the close button on the top right corner on Windows and Linux or top left for Mac, as the error occurs because the server is not really running when it fails to bind it.
No. I was using `screen` so as to be able to close the terminal window without terminating server. You can see http://linux.die.net/man/1/screen for more information. If I clicked the close button, the screen would just detach from the terminal and both, the screen and the server, would run farther, in the background.
I don't think this issue can be closed just because it has solution in some situations like when you use Minecraft_Server.exe or when you execute the server directly in a terminal.
You're saying the server is not really running, so it cannot stop. So just one condition to check if the server is running when typing "stop" command would be enough. It could function like now if the server is running and just send SIGTERM to itself when it isn't running. Simple, not opressing workaround.
Reopening, still an issue.
Attached latest.log and server.properties.
Confirmed for Minecraft 14w03b.
