java.lang.OutOfMemoryError: Java heap space Reading simple PDF

I am trying to convert a PDF pages to images just using the code from the documentation and I am getting a out of heap space error.
I have increased the JVM memory but I still get the error.

here is the code
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("input.pdf");

// Loop through all the pages of PDF file
for (int pageCount = 1; pageCount
{
// Create stream object to save the output image
java.io.OutputStream imageStream = new java.io.FileOutputStream("Converted_Image" + pageCount + ".jpg");


// Create Resolution object
com.aspose.pdf.devices.Resolution resolution = new com.aspose.pdf.devices.Resolution(300);
// Create JpegDevice object where second argument indicates the quality of resultant image
com.aspose.pdf.devices.JpegDevice jpegDevice = new com.aspose.pdf.devices.JpegDevice(resolution, 100);
// Convert a particular page and save the image to stream
jpegDevice.process(pdfDocument.getPages().get_Item(pageCount), imageStream);

// Close the stream
imageStream.close();
}



and this is the error.

I am not sure if this is important but the PC running this code is not connected to the internet.

Also it is running an a IBM Notes client.
