I did some testing, with the PDFs linked in [PDFBOX-4718](https://issues.apache.org/jira/browse/PDFBOX-4718) and [PDFBOX-4743](https://issues.apache.org/jira/browse/PDFBOX-4743). By overriding `transferClip` as ``` protected void transferClip(PDGraphicsState graphicsState, Graphics2D graphics) { List<GeneralPath> paths = graphicsState.getCurrentClippingPaths(); boolean allDone = true; for (GeneralPath path : paths) { if (!path.getPathIterator(null).isDone()) { allDone = false; break; } } if (allDone) { // PDFBOX-4821: avoid bug with java printing that empty clipping path is ignored by // replacing with empty rectangle, works because this is not an empty path graphics.setClip(new Rectangle()); return; } GeneralPath first = paths.get(0); graphics.setClip(first); for (int i = 1; i < paths.size(); i++) { graphics.clip(paths.get(i)); } } ``` , the OOM that occurred in the 1st PDF disappears, and the 2nd PDF is rendered much faster (still needs several seconds though). It seems that `SunGraphics2D.clip()` is doing a much better job than `Area.intersect()`. -- This is an automated message from the Apache Git Service.
