Description

As reported in PDFBOX-2546 by mkrivan

Caused by: java.lang.IllegalArgumentException: resourceDictionary is null
at org.apache.pdfbox.pdmodel.PDResources.<init>(PDResources.java:70)
at org.apache.pdfbox.multipdf.PDFMergerUtility.appendDocument(PDFMergerUtility.java:559)
at org.apache.pdfbox.multipdf.PDFMergerUtility.mergeDocuments(PDFMergerUtility.java:261)

The cause is an empty PDPage, i.e. without resources.

(Required; inheritable) A dictionary containing any resources required by the page (see 7.8.3, "Resource Dictionaries"). If the page requires no resources, the value of this entry shall be an empty dictionary. Omitting the entry entirely indicates that the resources shall be inherited from an ancestor node in the page tree.
