HTTP 400 with encoded umlauts in URL

I've updated shiro from version 1.4.2 to 1.7.1.

I have an rest-endpoint with an Pathvariable:

@RestController
@RequestMapping(value = "/inspektor/verjaehrungs-agent")
@Slf4j
public class MyRestController    

    @GetMapping("/profile/{name}")
    public Profile getProfile(@PathVariable final String name) {
        return service.getProfile(name);
    }

When requesting with the Pathvariable name "Test 123" everything works fine. 

When requesting with the Pathvariable name "Test ö" I'm getting an HTTP 400.

This error occurs also, when I encode the Pathvariable to "TEST%20%C3%B6".

Before the update, everything was fine.
