Kai Keggenhoff commented on PDFBOX-4478:
----------------------------------------
Unfortunately, some stamps still cause issues in 2.0.15. I attached
"bad_stamp-2.0.15.xfdf", which produces this error when I merge it :

it looks like the attribute value contains a LF/CR. When this error occurs, the
appearance is missing and only the outline of the stamp is shown when the user
selects the element.
I found two of the default stamps in Adobe Reader (german version) to cause
this :
- SBPreliminaryResults ("Vorläufige Ergebnisse")
- SBNotForPublicRelease ("Nicht zur Veröffentlichung")
