Spring oauth2 inserts hash sign instead of ? upon redirect to resource server with token

I have my Spring Boot application working with one exception. for implicit grant type after user approves access and redirected to resource server the authorization fails due to the hash sign instead of ? http://localhost:8080/testapp/test#access_token=621c8fce-4fe0-4893-9d96-63a7da8258ce&token_type=bearer&expires_in=26934&scope=trust%20read%20write

If manually corrected "#" to "?" the resource server validates the access token and provides services. I am using latest and greatest spring-security-oauth2 2.0.6.RELEASE Can somebody recommend the way how to override this?
