Mouse.setGrabbed(true) causes NPE on macosx

[Notch]

My code:

       Mouse.create();
        Mouse.setGrabbed(true);

The exception as reported over irc:

java.lang.NullPointerException
  at org.lwjgl.opengl.MacOSXDisplay.warpCursor(MacOSXDisplay.java:224)
  at org.lwjgl.opengl.MacOSXDisplay.grabMouse(MacOSXDisplay.java:281)
  at org.lwjgl.input.Mouse.setGrabbed(Mouse.java:514)
  at com.mojang.wom.WrathOfMagranon.b(SourceFile:162)

Maybe this is trivial, but are you sure you're calling Display.create() before this?
(Not too apparent from the exception, but if that's not the case then frame.bounds would be null in display)

I am, yes, but I'm not calling Display.makeCurrent() before.
