No error this time, but the screen remains black,
and fullscreen. I do hear the audio though.
UPDATE: I ran it again in windowed mode, I do see the opening graphics. Then I hit space, hear the audio, see the world with the two guns, then instant JVM crash with the same error as below. Conclusion: my system is utterly and thoroughly crappy.
Also, I ran it again without your changes, and this time the JVM crashed with an error relating to the Intel OpenGL driver so yup, shaders seem broken on my machine
