Eric Leleu resolved PDFBOX-1204.
--------------------------------

    Resolution: Fixed

Hi,

I thank you for the link.
It helped me a lot to find the fix.

As you have said, the problem is the partial font embedded by the OCR process.
When a glyph was used in a text, an exception was thrown when the glyph was missing or when the glyph width was inconsistent. This exception should not be thrown when the Rendering Mode is set to 3. I added this condition. 

I fixed the XMP error too.

Now the boyd.pdf file is considered as a valid PDF/A-1b.


BR,
Eric
