I don't know much about Tika, but this seems to be a bug in PDFBox.
See: https://issues.apache.org/jira/browse/PDFBOX-797
Yoz might also have a look at this:
http://stackoverflow.com/questions/7489206/error-while-parsing-binary-files-mostly-pdf
At least that's what I found when I googled the NPE.

I think this is because tika can't read the pdf file or this pdf file's format
has some error. But I can read this pdf file in Adobe Reader.
