Maruan Sahyoun commented on PDFBOX-2486:
----------------------------------------
[~tilman] as for the patch it might be better to make the getActions method
available in PDFieldTreeNode as AA entries are possible on terminal and non
terminal fields as this is defined in "Entries common to all field
dictionaries“ of the PDF spec and use that. The method needs to move up anyway.
