PDLineDashPattern fails as float[] is converted to List<float[]> instead of List<Float>

public COSBase getCOSObject()
{
  COSArray cos = new COSArray();
  cos.add(COSArrayList.converterToCOSArray(Arrays.asList(array)));
  cos.add(COSInteger.get(phase));
  return cos;
}

COSArray patternArray = new COSArray();
patternArray.setFloatArray(array);
cos.add(patternArray);
