Tika 1.2 PDF parse error - org.apache.pdfbox.cos.COSString cannot be cast to org.apache.pdfbox.cos.COSDictionary

[Phani Kumar Samudrala]

I am using Tika 1.2 JAVA API to extract text from a PDF, I am getting the 
following exception. I am getting this error for some PDF documents only and 
for some PDFs it is working fine. I couldn't figure it out a reason for this. 
When I tried using Tika 1.1 it works fine. Please let me if any of you have 
seen this error and how to fix this?

Here is the exception:

Here is the code snippet in JAVA:


String fileString = "C:/Bernard A J Am Coll Surg 2009.pdf";
                                     File file = new File(fileString );
                                     URL url = file.toURI().toURL();

                                     ParseContext context = new ParseContext();;
                                     Detector detector = new DefaultDetector();;
                                     Parser parser =  new 
AutoDetectParser(detector);;
                                     Metadata metadata = new Metadata();
                                     context.set(Parser.class, parser); 
//PPt,word,xlsx-- pdf,html
                                     ByteArrayOutputStream outputstream = new 
ByteArrayOutputStream();
                                                InputStream input = 
TikaInputStream.get(url, metadata);
                                                ContentHandler handler = new 
BodyContentHandler(outputstream);
                                                parser.parse(input, handler, 
metadata, context);

                                                input.close();
                                                outputstream.close();


Thanks
