Found a bug in the EMF output. And the fix is here.

java.lang.ArrayIndexOutOfBoundsException: 4
       at org.freehep.graphicsio.emf.EMFGraphics2D.draw(EMFGraphics2D.java:323)

Source Code:

if (shape instanceof CubicCurve2D) {
               CubicCurve2D curve = (CubicCurve2D)shape;
               writePen((BasicStroke)getStroke(), getColor());
               points[0].x = toUnit(curve.getX1());
               points[0].y = toUnit(curve.getY1());
               points[1].x = toUnit(curve.getCtrlX1());
               points[1].y = toUnit(curve.getCtrlY1());
               points[2].x = toUnit(curve.getCtrlX2());
               points[2].y = toUnit(curve.getCtrlY2());
               points[3].x = toUnit(curve.getX2());
               points[4].y = toUnit(curve.getY2()); <----- Needs to be changed to 3 not 4.
               os.writeTag(new PolyBezier(imageBounds, 4, points)); return;
           }
