Where to start with ClassCastException: org.apache.pdfbox.cos.COSFloat ?

[Mark Kerzner]

Hi,

I get this exception (see stack trace below), even though I am seemingly
catching it in my code, which says this

    public void parse(String fileName, Metadata metadata) {
        TikaInputStream inputStream = null;
        try {
            // the given input stream is closed by the parseToString method
(see Tika documentation)
            // we will close it just in case :)
            inputStream = TikaInputStream.get(new File(fileName));
            String text = tika.parseToString(inputStream,
metadata);             // --------_ exception happens here
            metadata.set(DocumentMetadataKeys.DOCUMENT_TEXT, text);
        } catch (Exception e) {
            // the show must still go on
            History.appendToHistory("Exception: " + e.getMessage());
            metadata.set(DocumentMetadataKeys.PROCESSING_EXCEPTION,
e.getMessage());
        } catch (OutOfMemoryError m) {
            History.appendToHistory("Memory Exception: " + m.getMessage());
            metadata.set(DocumentMetadataKeys.PROCESSING_EXCEPTION,
m.getMessage());
        } finally {
            if (inputStream != null) {
                try {
                    inputStream.close();
                } catch (Exception e) {
                    e.printStackTrace(System.out);
                }
            }
        }
    }

That's testing on Enron data set
