Description

I am getting: 

 

java.lang.ClassCastException: org.apache.pdfbox.cos.COSDictionary cannot be cast to org.apache.pdfbox.cos.COSArray

When executing the following code:

 

public byte[] extractTextPDFBox(String fileNamePath) throws PQException {

String UTF_8 = "UTF-8";

PDFLibraryProperties pdfLibraryProperties = PDFLibraryProperties.getInstance();
String regex = pdfLibraryProperties.getAsString(PDFLibraryConstants.REGEX_TO_REMOVE_FROM_EXTRACTED_TEXT);

byte[] bytesToReturn;
try

{ FileInputStream fis = new FileInputStream(new File(fileNamePath)); PDDocument pdfDoc = PDDocument.load(fis); PDFTextStripper pdfStripper = new PDFTextStripper(); String textFromPDF = pdfStripper.getText(pdfDoc); pdfDoc.close(); bytesToReturn = textFromPDF.getBytes(UTF_8); String textStr = new String(bytesToReturn).replaceAll(regex, PDFLibraryConstants.BLANK_SPACE); bytesToReturn = textStr.getBytes(); fis.close(); }

catch (IOException e)

{ pqUtilityLogger.logError(e.getMessage()); throw new PQException("e.getMessage()); }

return bytesToReturn;
}

 

It dies on String textFromPDF = pdfStripper.getText(pdfDoc);
