Andreas Lehmkühler resolved PDFBOX-1749.
----------------------------------------

    Resolution: Fixed

I've fixed the issue in revision 1535953. The parser now detects a premature end of file based on Tilmans comment. I introduced an additional method TTFDataStream#readUnsignedByte to avoid boilerplate code. It throws an exception if it detects a premature EOF.

Thanks for the report and the proposed fix!

> When parsing the attached TTF file with fontbox, I get an OutOfMemoryError (heap space) when parsing via an input stream. If I parse via a File, fontbox seems to never return.
