Tilman Hausherr commented on PDFBOX-4666:
-----------------------------------------
I need to think about this a bit, but it can be solved by checking whether the
actual resources object in {{DrawObject.process()}} is identical to the one of
{{context}}. This is not perfect, but it will catch this case, i.e. a direct
recursion.
