Digest authentication with spring security: 401 recieved as expected but with two WWW-Authenticate headers

When I send PUT request with correct username and password, it works fine. But when I send request with wrong password, I received 401 which is ok, but in I got 2 WWW-Authenticate headers:

Response headers: HTTP/1.1 401

WWW-Authenticate: Digest realm="NOKIA.COM", qop="auth", nonce="MTU1MjM3MDk2MDQ2MjpmOWNjYjVmNGU5ODA0ZmY0YWY0MjIxNDlhY2U2ODJiMQ=="

X-Content-Type-Options: nosniff X-XSS-Protection: 1; mode=block Cache-Control: no-cache, no-store, max-age=0, must-revalidate Pragma: no-cache Expires: 0 X-Frame-Options: DENY

WWW-Authenticate: Digest realm="NOKIA.COM", qop="auth", nonce="MTU1MjM3MDk2MDQ2NjoxOTQ4MDhjNzBjYjkyMGI1Y2Q2YjU3OGMyMTM2NmE3OQ=="

    digestAuthenticationEntry.setKey( "XXX" );
    digestAuthenticationEntry.setNonceValiditySeconds( 60 );
    return digestAuthenticationEntry;
}

Please someone can give me some help. Many thanks!

I solved this problem by myself. For request with incorrect auth, DigestAuthenticationEntryPoint was called twice by both digestFilter and exceptionFilter.

Overwrite DigestAuthenticationEntryPoint:

public class CustomDigestAuthenticationEntryPoint extends DigestAuthenticationEntryPoint
{
    @Override
    public void commence( HttpServletRequest request, HttpServletResponse response,
                          AuthenticationException authException )
        throws IOException, ServletException
    {
        HttpServletResponse httpResponse = ( HttpServletResponse ) response;
        String authHeader = httpResponse.getHeader( "WWW-Authenticate" );
        if( authHeader != null )
        {
            httpResponse.sendError( HttpStatus.UNAUTHORIZED.value(), HttpStatus.UNAUTHORIZED.getReasonPhrase() );
        }
        else
        {
            super.commence( request, httpResponse, authException );
        }
    }
}
