Tilman Hausherr commented on PDFBOX-4828:
-----------------------------------------
It happened in PDFBOX-4580. The warning "FeatureRecord array not alphabetically
sorted by FeatureTag: init < isol" is related to the problem. Removing the
"return" in the code makes it work again. The change is there to detect corrupt
fonts. ArialUni.ttf is obviously not a corrupt font but it does not follow the
specification.
So there are two things to do:
* make the check more relaxed so that only non alphanum names are checked
* find out why the ArrayIndexOutOfBoundsException. My guess is that we skip
one table but not another table that references it.
