Tilman,
I am very sorry that I did not share what I was actually trying to do. I did not really understand the problem yesterday.
Here is an example offending document:
https://dl.dropboxusercontent.com/u/3103884/dev/RenewalUM_SD.pdf

OK, I found the mistake. I'll do a bit more tests and then commit the change.

It has been fixed. A snapshot should be available within a few hours.

I am stuck on this exception from JPXFilter.encode() from some documents that I am trying to merge:

I would not mind if I could simply skip the image. I am unable to figure out how to complete the merge when this exception occurs. Is there some way to do that?

  From the same batch of PDFs I also sometimes get WARN
org.apache.pdfbox.filter.DCTFilter - DCTFilter#encode is not implemented yet, skipping this stream.

Would it be better if the JPXFilter just wrote a message like the DCTFilter does rather than throwing an Exception?
Oh, this is a bug. A merge should be possible without decoding / re-encoding images.

I wish you had said this before I wrote the other answer.

Can you share the files where one of these exception happens?
