PDFBox: Remove a single field from PDF
<p>The simplest way I can describe the problem is that we to use PDFbox to remove only one field from a PDF that is sent to us from HelloSign.  (e.g. Credit Card Number)</p>

<ol>
<li>The data in question will always be on the last page, and it will always be at the same coordinates in the page.</li>
<li>The data needs to be completely removed from the PDF.  We can't simply change the font to white or draw a box on top as it will still be selectable, and thus, can be copied.</li>
<li>Only that one field can be removed.  We still need the other fields and the signatures.</li>
<li>I've created a sample document and uploaded it to Dropbox. <a href="https://www.dropbox.com/s/oyv1vjyhkmao1t1/input.pdf?dl=0" rel="nofollow noreferrer">input.pdf</a></li>
<li>For the sake of this question, let's assume the field to be removed is the Street Address from the file I uploaded.  Not the City, State, Zip, Signatures, or Dates.  (In real life it will be a sensitive data field like a Credit Card Number or SSN.)</li>
</ol>

<p>I'm putting a loooong-winded explanation of the problem and what I've tried so far in the first comment below.</p>
