Jukka Zitting commented on TIKA-778:
------------------------------------
Looks like the problem is coming from the HTML serializer rather than from
PDFBox.
I can't reproduce this locally. Instead of sharing the test PDF here publicly,
is it possible for you to send it to me in private? Alternatively, can you
check if the following command works as expected (should produce valid HTML):
{code}
$ java -jar tika-app-1.0.jar --html /path/to/test.pdf
{code}
> NullPointerException in tika-app, parsing PDF content

> I tried the same pdf files (and can switch forth and back between version
> 0.10 and 1.0, this behavior is stable) and it looks like the exact same
> pdfbox version is inside the tika-app-0.10.jar and tika-app-1.0.jar. It would
> be great if version 1.0 could do what 0.10 can. Sorry that I cannot provide
> the pdf.
