Amir, Paragraphs are separated by "\n", so it sounds feasible to split the text by "\n". But the text extracted from the PDF seems to contain many "\n"s and would make it impossible to extract paragraphs. I even don't think there is a way to do this using PDFBox.
One possible solution would be constructing classifiers to discriminate the boundary between different paragraphs. I also suggest you get to know the subject "topic boundary detection".
