Related to #11041.

I'm trying to validate @PathVariable and @RequestBody in one method. MethodValidationPostProcessor is registered. Simplified Controller looks like this:

@RestController
@Validated
public class MyController {
    @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
    public ResponseEntity method_name(@PathVariable @NotNull String id, @Valid @RequestBody Body body) {
        /// Some code
    }
}

I noticed that request body validation is triggered twice - it wouldn't be an issue if it weren't custom ConstraintValidator with injected bean:

public class CustomValidator implements ConstraintValidator<Body, String> {

	@Autowired
	private BodyVerificator bodyVerificator;
...

For first validation run the bean is injected properly, and for second run it's null so it results in NPE. Workaround is to either not use method parameter validation at all, or to annotate @RequestBody with @Validated so not mix @Validated and @Valid. I would actually prefer to have @PathVariable bean validation support in Spring like in #11041.
