Description

If you trying to load very large PDF file (over 2GB), you get java.io.IOException: java.lang.NumberFormatException: For input string: "2313730984".

It fails in COSParser.java in parseXrefTable(long startByteOffset). On the line 2006, if Integer.parseInt(splitString[1]) reads number which is bigger than maximum int.
