Tilman Hausherr resolved PDFBOX-2020.
-------------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0
1.8.7
Assignee: Tilman Hausherr (was: Guillaume Bailleul)
Unlike in april, I understand the problem now: preflight was searching for a
color space when there are no colorspaces at all in the resources. The new code
avoids the NPE and will simply return "The ColorSpace is unknown".
[~gbm.bailleul] The failing isartor tests were handled in PDFBOX-2179.
[~pikachuman] Please get a snapshot version (see link I posted previously in
the other issue) and reopen this one if it doesn't work. Re "the colorspace is
unknown": you can verify this by opening your file with the PDFDebugger command
line app. (If you don't know how to find it in the "tree", I can attach a
screenshot)
