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

Question

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

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

Aqui está a saída de mdls para um arquivo que exibe "Java Source" :
