The exception you are experiencing is described here. The problem is that Java believes you are attempting to run code which depends upon a mouse, keyboard, or display being available and one is not.

One major thing to note: On the Minecraft website, it is stated: "Download Minecraft.jar (86 KB). The jar is executable and should work as-is, also please use Oracle's JVM." ( ). That said, my Fedora 21 system is using the OpenJDK just like yours and it works without issue.

If you execute yum list installed java*, do you see that you have both the java-1.8.0-openjdk.x86_64 package and the java-1.8.0-openjdk-headless.x86_64 package installed? 'Cause if you have only the latter, that might be the source of the trouble.

@bitwiseoperator I have my main screen turned off in settings, as half of the time it doesn't work. I think that might be why it throws the HeadlessException. I also have the openjdk headless and the regular open jdk installed.

I fixed it. All I had to do was run sudo dnf install java-1.8.0-openjdk-devel

The headless java is installed by default. You need to install the full (GUI) version:

dnf install java-1.8.0-openjdk

The devel packages (mentioned in your answer) are not required for minecraft.

The java-1.8.0-openjdk package was the final resolution in my case for this error message. . Thanks so much. I only wish this tip was closer to the top :) Resolved for FC23.
