Description

There seems a problem with de-/serialization of GrantType}}s. When using the Oltu client for own services, the {{GrantType is serialized by the toString() method, which returns lower case identifiers.

        OAuthClientRequest request = OAuthClientRequest
                .tokenLocation("http://localhost:8080" + CONTEXT_PATH + "/oauth2/token")
                .setClientId("test")
                .setGrantType(GrantType.PASSWORD)
                .setUsername(email)
                .setPassword(password)
                .buildBodyMessage();
        OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
        OAuthJSONAccessTokenResponse oauthResponse = oAuthClient.accessToken(request);

While on the server OAuthUnauthenticatedTokenRequest's constructor will call GrantType.valueOf(String), which only accepts upper case identifiers.

That results in an exception:
