Hello, I will do that.
However: The pdfbox-documentation says: "You can have multiple threads each accessing their own PDDocument object." (https://pdfbox.apache.org/1.8/faq.html) Maybe there should be a hint, that this also depends on optional dependencies as "JBIG2 ImageIO", "JBIG2-Image-Decoder" and "JAI Image I/O Tools Core" (https://pdfbox.apache.org/2.0/dependencies.html ) Felix Gesendet: Montag, 14.
