Could you please elaborate? I am not sure how to reproduce. Screenshots are fine too.

[linsui]

There are icons for the attached files.

In fact these files are all PDF and the icons should be

I change the type from application/pdf to PDF in the bibtex.

1. Add a file with application/pdf type

• What version of Linux is this?

• What method do you use to attach your pdf to JabRef? e.g. Lookup> Search for unlinked local files (Shift+F7) or is it some other way?

• Could you please provide the resulting bibtex entry? Basically the data in the {} biblatex source tab.
  How does it look like? Does it look roughly like this?

  @application/pdf{thecitationkey,
  file         = {:yourfile.pdf:PDF},
  }

What version of Linux is this?

NixOS

What method do you use to attach your pdf to JabRef?

It's exported from Zotero. I can also download a entry with jabref and change the type manully. The result is the same.

Could you please provide the resulting bibtex entry?

file = {Full Text PDF:files/187/Norkin 等。 - 2014 - In-Loop Filters in HEVC.pdf:application/pdf},

Replacing application/pdf with PDF after the last colon works. So I guess JabRef does not recognize this when parsing.
file = {Full Text PDF:files/187/Norkin 等。 - 2014 - In-Loop Filters in HEVC.pdf:PDF},

[linsui]

Yes, application/pdf is not recognized as PDF.

return externalFileTypes.fromLinkedFile(linkedFiles.get(0), false)

false needs to the changed to true, so that JabRef correctly searches registered external file types base on mime type.
application/x-latex or any other mime type defined with an icon in the Preference -> External file types
