CompletionItem.kind is incorrect for interfaces

[yyoncho]

      {
        "label": "Runnable - java.lang",
        "kind": 7,
        "sortText": "999999164",
        "filterText": "Runnable",
        "insertText": "Runnable",
        "data": {
          "decl_signature": "Ljava.lang.Runnable;",
          "pid": "217",
          "rid": "86",
          "uri": "file:///.../src/main/java/temp/App.java"
        }
      },

Runnable is interface and jdt ls should return kind = 8(interface) not kind = 7(class)

I can confirm the issue exists.

https://github.com/eclipse/eclipse.jdt.ls/blob/fc6b40e58808d23a324628a1e79e50f117c534de/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/contentassist/CompletionProposalRequestor.java#L51

CompletionItemKind.Interface is not in the supported kinds. No idea why. CompletionProposals have flags and it should be easy to determine if TYPE_REF has the Flags.AccInterface flag.

It seems the proposal flags aren't used at all, wonder why that is.

We don't always write perfect code ;-)

And yes, it's pretty easy to fix once we use CompletionProposal.getFlags():
