memory-usage

I am looking for a Java library that let's you write large PDFs sequentially with a minimum amount of memory. Most of the libraries I had a look at has to build up the document in memory first before you can actually write it.

The problem I have to deal with are OutOfMemoryErrors. It would be great if I could flush the writer programmatically whenever needed e.g. for each page.

Does anyone have any recommendations? I need something with a license along the lines of the LGPL (so not the GPL or the Affero GPL that iText uses).
