doFilter method invoking twice ?

doFilter method inside class RestTokenValidationFilter in invoking twice on every call and inside doFilter method there is a call for authentication which is also invoking twice any solution to reduce it ?

Start by locating RestTokenValidationFilter and tracing every path that reaches doFilter, including the authentication call described in the issue. Confirm whether the method is entered twice per request and identify the request or filter configuration responsible; done means the duplicate invocation is explained and the behavior is corrected or documented.
