Yes my code contains a "reader.removeUnusedObjects();" but it seems so,
that this method can not remove my unecessary objects.
The PDF-analyzer "PDFVole" lists many "global objects" under the entry

My example PDF contains 2537 entries under "global objects". After
optimizing the PDF with Ghostscript only 50 objects listed as "global
objects".
