IMAGINGJAVA-8037 Display the correct exception instead of: “Object reference not set to an instance of an object.” exception.

String fileName = "áóêëåò.cmx";
String baseFolder = "D:\\";
String inputFilePath = baseFolder + fileName;

}

IMAGINGJAVA-8028 Speed up resize method in Aspose.Imaging

class Stopwatch
{
	private long startTime;
	private long endTime;

	public void start()
	{
		startTime = System.nanoTime();
	}

	public void stop()
	{
		endTime = System.nanoTime();
	}

	long getElapsedMilliseconds()
	{
		return (endTime - startTime) / 1000000;
	}
}

{
        "resultyuv420_watermark.jp2", "resultyuv422_watermark.jp2",
        "resultyuv444_watermark.jp2"
};

for (String file : files)
{
       try (RasterImage image = (RasterImage)Image.load(file))
       {
