Description

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
}
