I'm trying to read an existing Excel file with the following code:
File billFile = new File(bill.getFilePathOnServer());
        InputStream inp;
        Workbook workbook;
        try {
            inp = new FileInputStream(billFile);
            workbook = WorkbookFactory.create(inp);
        } catch (Exception e) {
            throw new
CannotReadBillFileException(billFile.getAbsolutePath());
        }

The file exists, it can be read, but WorbookFactory throws the following
exception:

java.io.IOException: block[ 44016 ] already removed - does your POIFS have
circular or duplicate block references?

Any idea what's wrong?
