This happens with [^poppler-14433-0.pdf] because {{PDFieldFactory.createField}} in {{AcroFormOrphanWidgetsProcessor.java:130}} returns null.

> Key: PDFBOX-3891
> URL: https://issues.apache.org/jira/browse/PDFBOX-3891
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm, Utilities
> Affects Versions: 2.0.7
> Reporter: Haiko Strotbek
> Assignee: Maruan Sahyoun
> Priority: Major
> Fix For: 2.0.22, 3.0.0 PDFBox
>
> Attachments: MergeTest.java, merge-test-acrobat.pdf, merge-test-fields-added-merged.pdf, merge-test-merged.pdf, merge-test-na-acrobat.pdf, merge-test-na.pdf, merge-test.pdf, poppler-14433-0.pdf

>
> When using PDFMergerUtility to merge the attached PDF twice into one document there may be data missing.
> To be more specific: In this case the data on page 1 looks fine, but page 28 is empty. My expectation is that page 28 is identical to page 1 (the document has 27 pages).
> Of course that's not a common use case. But I can reproduce this behaviour with other documents which are not identical, but similar.
> I think this might be related to PDFBOX-3111 and PDFBOX-3218.
> What is the trigger for this and is there a workaround?
