Parameter not checked correctly when AliasFor is used in annotation

[fjakop]

Given an annotated method like

import org.springframework.web.bind.annotation.*;

public class MyClass {
  @GetMapping(produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
  public ResponseEntity<Map<String, Result>> myMethod() { ... } 
}

the following validation fails

@Test
public void annotations() throws Exception {
    AnnotationValidator.validate().exactly()
            .annotation(type(GetMapping.class)
                .param("produces", MediaType.APPLICATION_JSON_UTF8_VALUE))
            .forMethod(MyClass.class.getDeclaredMethod("myMethod"));
} 

the functional equal annotated method is validated (when adding the method param)

@RequestMapping(method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_UTF8_VALUE)
public ResponseEntity<Map<String, Result>> myMethod() { ... } 

We are using version 1.2.
