             Summary: PDImageXObject and UnsupportedOperationException combined with JPEGFactory
                 Key: PDFBOX-4968
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4968
             Project: PDFBox
          Issue Type: Bug
          Components: PDModel, XmpBox
    Affects Versions: 2.0.0
         Environment: Windows 10 (64 Bit), Java 11.0.8, Netbeans 11.2
            Reporter: Robert Fink
         Attachments: SampleApplication.java

The goal is to add Metadata to an image within the PDF document.

The PDImageXObject is created by the JPEGFactory class and the method createFromImage(pdDocument, bufferedImage).
The PDImageXObject itself will be created but when trying to add metadata to it an error is thrown. Catching the UnsupportedOperationException would work.

It doesn't work with Java 8 and Java 11 starting from PDFBox 2.0.0.
