Openjdk: Program closes shortly after launching

[Andrew]

Ubuntu 11.04
package version: 6b22-1.10.2-0ubuntu1~11.04.1 (openjdk-6-jre)

What I expected to happen: I start the program, the program allows me to log in, then I play the game.

Here's the error message:

I started minecraft.jar by using the command java -jar minecraft.jar, then I logged in. Then, I logged in, and then the program closed. This happened several times.
