Tilman Hausherr commented on PDFBOX-5792:
-----------------------------------------
Thanks for reporting this. I think there is a logic mistake in
{{fixDestinations()}} because it is called for every destination document, so
the destination page is sometimes set to null prematurely. I need to rethink
this.
If this blocks you, then the best is not to revert to the old version, but to
copy the splitter code (because 3.0.1 has other bugs that may be related to
splitting!), change {{fixDestinations()}} so that it checks for null at the
line that crashes. The result will be that SOME of the local destination links
won't work (which is closer to the old behaviour, where NO links worked).
