Tilman Hausherr commented on PDFBOX-5952:
-----------------------------------------
Please don't resolve it, because 1) it wasn't resolved, 2) there might be a
solution in the future. I don't have a good idea, but maybe others in the team
will. Another possible solution would be some sort of global weak cache for ICC
profiles, because it's the ICC operations that are costly in time.
