macOS 10.13.4 O Finder exibe kMDItemKind para alguns arquivos .java como “Source Code”, mas como “Java Source” para outros

No macOS 10.13.4, para alguns .javaarquivos, o Finder é exibido "Java Source"para kMDItemKind(ou seja, a coluna "Tipo" na visualização "Lista"), mas para alguns outros .javaarquivos, ele é exibido "Source Code", mesmo dentro da mesma pasta.

Como posso garantir que todos os .javaarquivos tenham consistentemente kMDItemKind = "Java Source"?

Aqui está a saída de mdlsum arquivo que exibe "Java Source":
