collectionFormat always multi

[deripas]

I using latest version 2.9.2

Linked Issues:

• collectionFormat is always multi collectionFormat is always multi #1442

• collectionFormat problem collectionFormat problem #1946

This Issues closed, but problem with collectionFormat not resolve yet!

I use @ApiImplicitParam annotation, like this:

 @ApiImplicitParam(name = "id", paramType = "path", allowMultiple = true, dataType = "long", collectionFormat = "csv")

Swagger result, its generate with collectionFormat: multi.

      parameters:
        - name: id
          in: path
          required: false
          type: array
          items:
            type: integer
            format: int64
          collectionFormat: multi

collectionFormat ignored.

I want to believe in the imminent hot fix 2.9.3
Thank you!

PS this patch based on 2.9.2 tag.
