For me, I fixed error as:
/**
* Constructor for reading a Type0 font from a PDF file.
*
* @param fontDictionary The font dictionary according to the PDF
specification.
*/
public PDType0Font(COSDictionary fontDictionary) throws IOException
{
super(fontDictionary);
COSArray descendantFonts =
(COSArray)dict.getDictionaryObject(COSName.DESCENDANT_FONTS);
COSDictionary descendantFontDictionary = (COSDictionary)
descendantFonts.getObject(0);
if (descendantFontDictionary == null)
{
throw new IOException("Missing descendant font dictionary");
}
descendantFont =
PDFontFactory.createDescendantFont(descendantFontDictionary, this);
readEncoding();
fetchCMapUCS2();
//!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
PDType0Font parentFont = PDType0Font.load(new PDDocument(), new
File("c:\\Windows\\Fonts\\arial.ttf")); //kostya!!!!
embedder = parentFont.embedder; //kostya!!!!
}

embedder has not been initialized in
