Spring Boot Swagger 2 UI Oauth2 configuration

I have some troubles getting Swagger UI running for my OAuth2 secured API with the current 2.0.0 release.

I guess I’m missing something…

I used following Configuration

    @Bean
    public Docket apiDocumentation() {
        return new Docket(DocumentationType.SWAGGER_2).groupName("api").apiInfo(apiInfo())
                .select().paths(internalPaths()).build()
                .securitySchemes(newArrayList(securitySchema()))
                .securityContexts(newArrayList(securityContext()));
    }

    public static final String securitySchemaOAuth2 = "oauth2schema";
    public static final String authorizationScopeGlobal = "global";
    public static final String authorizationScopeGlobalDesc ="accessEverything";

    private OAuth securitySchema() {
        AuthorizationScope authorizationScope = new AuthorizationScope(authorizationScopeGlobal, authorizationScopeGlobal);
        LoginEndpoint loginEndpoint = new LoginEndpoint("http://localhost:9999/sso/login");
        GrantType grantType = new ImplicitGrant(loginEndpoint, "access_token");
        return new OAuth(securitySchemaOAuth2, newArrayList(authorizationScope), newArrayList(grantType));
    }

    private SecurityContext securityContext() {
        return SecurityContext.builder()
                .securityReferences(defaultAuth())
                .forPaths(internalPaths())
                .build();
    }

    private List<SecurityReference> defaultAuth() {
        AuthorizationScope authorizationScope
                = new AuthorizationScope(authorizationScopeGlobal, authorizationScopeGlobalDesc);
        AuthorizationScope[] authorizationScopes = new AuthorizationScope[1];
        authorizationScopes[0] = authorizationScope;
        return newArrayList(
                new SecurityReference(securitySchemaOAuth2, authorizationScopes));
    }

My API methods are annotated like that

@RequestMapping(value = "/languageFile", method = RequestMethod.GET)
    @ApiOperation(value = "Fetches the language file of a given or the default locale",
                  authorizations = {@Authorization(value = SwaggerConfig.securitySchemaOAuth2, type = "oauth2", scopes =
                          {@AuthorizationScope( scope = SwaggerConfig.authorizationScopeGlobal, description = SwaggerConfig.authorizationScopeGlobalDesc)})})
    public I18NGetLanguageFileResponse getLanguageFile(@RequestParam(defaultValue = TechnicalConfig.defaultLocaleString, value = "locale", required = false) String localeString) {

The Result

The problem now is that the authentication button appears in Swagger UI but isn’t invokable. There isn’t even any js attachted to this button.
