Resolution: Not A Problem
Ah thanks. And coincidentally it was me who opened that issue and even worked on it a bit.

> Project: PDFBox

> We encounter some pdf containing inline images, and when rendering some of them trigger exceptions like :

> This seems to be caused by a NL=0x0a byte just after ID, and it seems that the parser expects the first image data byte right after ID.
> A space after ID seems valid according to pdf reference 1.7 example 4.30
