Add this to PdfCopy:
public void freeReader(PdfReader reader) throws IOException {
indirectMap.remove(reader);
if (currentPdfReaderInstance != null) {
if (currentPdfReaderInstance.getReader() == reader) {
try {
currentPdfReaderInstance.getReader().close();
currentPdfReaderInstance.getReaderFile().close();
}
catch (IOException ioe) {
// empty on purpose
}
currentPdfReaderInstance = null;
}
}
}
