      import java.awt.geom.Point2D;
      
      def width = 240.0
      def radius = width / 3.0
       
      new Point2D.Double(x: 0, y: radius * 2 / 4)

      If you change the Groovy code to:

      import java.awt.geom.Point2D;
      
      def width = 240.0
      def radius = width / 3.0
       
      new Point2D.Double(x: 0, y: radius * 2D / 4D)
      

      it works ok.
