Hello Maruan, In regards to the AutoSize changes; The text fits better (no longer is cutoff by the field boundaries) :). The text is higher than normal, as mentioned by another, but is sufficient for my use.
Unfortunately, when converting my project from 1.8.9 to the latest 2.0.0 snapshot, I've encountered some new problems. I will send those in a new email.

Its unfortunate it isn't listed in the spec so everyone can be the same. I imagine the calculation could get quite complicated. Yes I can use a newer version. I'm not very familiar with software life cycle, will I need to wait for the RC for a fix? If so, any guesses as to when that might be? I committed some changes to the text formatting specially for autosize text. You can either build from source or use the snapshot as soon as it is available at http://pdfbox.apache.org/download.cgi#snapshots <http://pdfbox.apache.org/download.cgi#snapshots> Please let me know if it improves the output you get.
