Tilman Hausherr reopened PDFBOX-2479:
-------------------------------------
I disagree with this change:
The method is used only by preflight and preflight needs to know if an ICC
profile can't be read. I don't have the PDF/A spec but if the alternate
colorspace is used, this means that the PDF won't look exactly like intended
and that is the point of PDF/A. I tried the PDFA checker of pdftools this
morning and they mention that the ICC profile is broken. What I had in mind
(and already tested but I then went to work) was to throw an exception, and to
catch the exception in preflight and then add it to the error table.
