Java error during server startup

When I start a java Minecraft server, I get a message from Sun that says the code is using a “terminally deprecated method”. Here’s the message:

C:\Users\Jim\AppData\Roaming\.MCServer - Gideon>java -Xmx2G -Xms2G -jar server.jar nogui --bonusChest

The game starts normally, so it seems this is just a warning from Sun. But it implies that the code is going to fail at some point in the future.
