Michael,

Will do that, thank you for the hint.
It is not the first time I try do find this. When I investigated in the past I really found that the submitted data was shreddered.
I am pretty sure this is not an iText issue and the error message is correct, but I haven't any clue what causes the data to be shreddered during the submit process.

Have you considered dumping baos.toByteArray() to an unique file whenever
that exception occurs and inspect what actually has been submitted to your
web application?
