Hi Tom, PDF is not a format which is build sequentially but a Random Access format. In order to lower the memory consumption you can pass a temp file which will be used to store intermediate data.
Take a look at http://pdfbox.apache.org/docs/1.8.3/javadocs/org/apache/pdfbox/pdmodel/PDDocument.html especially the load and loadNonSeq (which is the preferred method) description PDFStreamParser is used internally to parse PDF streams (a PDF internal structure).
