-----------------------------------------
I did send a reply this morning with an apology for not responding, but I did
see the post a few weeks ago. You can write to the mailing list, the best is
usually the users mailing list.
Please come back here when you've tested your implementation (with a copy of
the class). My little implementation is really a quickie, so I may have
forgotten something.

> Overriding loadPDF allows subclasses to load overlays from sources different
> than File objects, for example from InputStreams or byte arrays (mostly
> through PDDocument.load overloads).
> For example:
> {code:java}
> Overlay overlay = new Overlay() {
> @Override
> protected PDDocument loadPDF(String pdfName) throws IOException {
> return PDDocument.load(overlayStreams.get(pdfName));
> }
> };
> {code}
