Thread: error - No source code is available for type

I am using libgdx and getting a error. I am not sure what this error means and how can I fix this?

error:

	[ERROR] [com.ia.asteroid.GwtDefinition] - Line 41: No source code is available for type java.awt.geom.Line2D.Float; did you forget to inherit a required module?
	[ERROR] [com.ia.asteroid.GwtDefinition] - Line 42: No source code is available for type java.awt.geom.Point2D.Float; did you forget to inherit a required module?
