The null is a bug in the sense that the pdf has an empty ToUnicode map and
iText expected a good map. It's fixed in the SVN.

I didn't see the question on the internal support list yet.
Am I correct that you posted the question twice, once on the free list,
once on the customer's list?
Because I can't see it on the customer's support list.
Anyway, this is the syntax inside your PDF:

Why is some of the text duplicated?
Because the text occurs twice in the PDF syntax.
For instance: (!"#$%&'\(%\)*+) stands for "Implications".
It occurs on two places:
coordinate 69.12, 742.98; and
coordinate 67.98239, 744.1204.
Because the two separate instances of the word are so close to each
other, you see it only once in the PDF, but that doesn't mean it isn't
there twice.
As for the 'null', you have some odd String <0001> that separates the
words in those first sentences.
Hope this helps.
