Error while converting color DWG to PDF (UseObjectColor mode)

I modified code of demo ConvertDWGFileToPDF to convert my color image from DWG to PDF

package com.aspose.cad.examples.DWGDrawings;

import com.aspose.cad.*;
import com.aspose.cad.examples.Utils.Utils;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PdfOptions;
import com.aspose.cad.fileformats.cad.CadDrawTypeMode;

import java.awt.Image;

public class ConvertDWGFileToPDF {

public static void main(String[] args) {
	// The path to the resource directory.
    String dwgFile = "ColorDemo.dwg";
	String dataDir = Utils.getDataDir(ConvertDWGFileToPDF.class) + "DWGDrawings/";

	//ExStart:ConvertDWGFileToPDF
    String srcFile = dataDir + dwgFile;
	
	 com.aspose.cad.Image objImage = com.aspose.cad.Image.load(srcFile);

	 // Create an instance of CadRasterizationOptions and set its various properties
	CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
            rasterizationOptions.setAutomaticLayoutsScaling(true);
            rasterizationOptions.setDrawType(CadDrawTypeMode.UseObjectColor);
            //rasterizationOptions.setBackgroundColor(Color.getWhite());
            rasterizationOptions.setPageWidth(1600);
            rasterizationOptions.setPageHeight(1600);
            // Create an instance of PdfOptions
            PdfOptions pdfOptions = new PdfOptions();
            pdfOptions.setVectorRasterizationOptions(rasterizationOptions);
            // Export the DWG to PDF
            objImage.save(dataDir + dwgFile + ".pdf", pdfOptions);
            //ExEnd:ConvertDWGFileToPDF
}

}

While executing code i’ve got error:

Exception in thread “main” class com.aspose.cad.cadexceptions.ImageSaveException: Image saving failed. —> class com.aspose.cad.cadexceptions.ImageSaveException: Image export failed. Error during PDF export: index —> java.lang.RuntimeException: Error during PDF export: index

When I replace UseObjectColor to UseDrawColor the code above works fine
