Implit grant does not support the issuance of refresh tokens

[Tsuyoshi Yoshizawa]

http://tools.ietf.org/html/rfc6749#section-4.2

The implicit grant type is used to obtain access tokens (it does not support the issuance of refresh tokens)

The authorization server MUST NOT issue a refresh token.

• We should not return refresh token in response when grant is Implicit
• ImplicitGrantHandler should not call AuthorizationHandler#refreshAccessToken

@satabin Is this specification correct, right?
Then, I will fix this problem.

[Lucas Satabin]

Right, I missed this point. Refresh token are indeed not issued in this flow.
