Maruan Sahyoun commented on PDFBOX-6162:
----------------------------------------
[~tilman] if you're fine with it feel free to resolve the issue. I'll try to
move on to the next. We can look at code quality in another step IMHO. Would it
make sense to add that to Sonar too? How?
> Reuse of symbol context not properly supported

> Considering the name of the file, I assume this means we don't support the
> reuse of symbols correctly. The file has at least 4 different symbol
> segments. From what I see on
> https://github.com/SerenityOS/serenity/blob/master/Tests/LibGfx/test-inputs/jbig2/json/bitmap-symbol-context-reuse.json
> the text segment refers to the symbols of the 4 previous symbol segments, and
> the symbol segments indicate some logic to retain the symbols of previous
> segments, so one will have to investigate what happens.
