> It takes ~600mb of memory after loading a single page document (with embeded fonts). Memory usage grows slightly with the increasing number of pages in the document. What's wrong with this PDF (I've not noticed strange patterns in PDF debugger) ?
> {code}
> public static void main(String[] args) throws Exception {
> File in = new File("out2.pdf");
> File out = new File("out2_.pdf");
> if (!out.exists()) {
> out.createNewFile();

> InputStream inputStream = null;
> OutputStream outputStream = null;
> System.out.println("start pdf 2 pdf");
> PDDocument doc = null;
> try {
> final long startTime = System.currentTimeMillis();
> inputStream = new BufferedInputStream(new FileInputStream(in));
> outputStream = new BufferedOutputStream(new FileOutputStream(out));
> System.out.println(MessageFormat.format("before loading totalMemory: {0}, free: {1}, max: {2}",
> Runtime.getRuntime().totalMemory(),
> Runtime.getRuntime().freeMemory(),
> Runtime.getRuntime().maxMemory()));
> doc = PDDocument.load(inputStream, MemoryUsageSetting.setupTempFileOnly());
