Andreas Lehmkühler resolved PDFBOX-3826.
----------------------------------------
Resolution: Fixed
The behaviour was adjusted as follows:
- PDFBox closes all resources which are created by PDFBox itself
- All instances of TrueTypeFont which are passed by the user won't be closed
anymore
Set to resolved
> NPE if RAFDataStream.getCurrentPosition() when TrueTypeFont created from file
> is reused

> This happens only if the TrueTypeFont is created from a file, not when it is
> created from a stream (PDFBOX-3337). It worked in 2.0.0 but no longer since
> 2.0.1.
