> Project: PDFBox

> org.apache.pdfbox.cos.COSDocument.close() does not close the streams and
> causing therefore a growing memory leak. Supposed fix:
> public void close() throws IOException {
> // if (!closed) {
> // scratchFile.close();
> // if (tmpFile != null) {
> // tmpFile.delete();
> // }
> // closed = true;
> // }
> // begin Robert Scharpf
> closed = true;
> if (scratchFile != null) {
> try {
> scratchFile.close();
> } catch (Exception e) {
> }
> }
> scratchFile = null;
> if (tmpFile != null) {
> try {
> tmpFile.delete();
> } catch (Exception e) {
> }
> }
> tmpFile = null;
> List<COSObject> list = getObjectsByType(COSName.OBJ_STM);
> if (list != null) {
> for (COSObject objStream : list) {
> COSStream stream = (COSStream) objStream.getObject();
> stream.close();
> }
> }
> // end Robert Scharpf
> }
