This is a bit strange, since I thought that this bug was fixed with PDFBOX-3488
PdfBox is running on a linux server but when I tried to access the PDFs I
failed to find the right one (over 1 million docs on that server).
On the other hand the fix linked in the ticket points to the following
implementation:
{code:java}
@Override
public GeneralPath getPath(int code) throws IOException{
if (ttf.getGlyph() == null){
throw new IOException("glyf table is missing in font " + getName());
} {code}
which does not exist anymore in 2.0.3 or higher:
{code:java}
@Override
public GeneralPath getPath(int code) throws IOException{
int gid = codeToGID(code);
GlyphData glyph = ttf.getGlyph().getGlyph(gid); {code}
Any idea why an NPE might occur?
`ttf` might be null or `getGlyph` returns null?

*Since some time we get the following Nullpointer when using PdfBox:*
