One note parsing problems

[KnispoDisig]

Hello Nicholas, now I ran into a problem with parsing files .one and .onetoc2 =(

I saw your contribution to tika in which you introduced support of tika parsing and I really appreciate it. But now I'm trying to parse an ordinary .one file but I see that it's impossible. I get stack trace that will be attached to this email.

Is this really some problems with parser or I'm doing something wrong?

Thank you in advance!
