You're right. I think I've nailed it down. After recompiling PdfName, I
see that it is blowing up on line 782 of PdfName. This is where it has this
piece of code:
778 public PdfName(String name) {
779 super(PdfObject.NAME);
780 int length = name.length();
781 if (length > 127) {
782 throw new IllegalArgumentException("The name is too long (" +
bytes.length +").");
783 }
The NullPointerException is actually happening on the "throw new
IllegalArgumentException". bytes is null.
The problem with the PDF is that we had a checkbox whose export value was
greater than 127 bytes.

It's probably a broken PDF (just because it opens in Acrobat doesn't
mean it's 100% correct). You may try with the version at itextpdf.sf.net
that has some more tricks to read broken PDFs.
