This code works fine if written like this

@RestController
@RequestMapping("/system/test")
public class SystemUserController {
    @GetMapping
    public ResponseResult index(@RequestParam LinkedHashMap<String, Object> params) {
        return ResponseResult.success();
    }
}

I want to encapsulate LinkedHashMap, so the call will report an error argument type mismatch

public class MyLinkedHashMap extends LinkedHashMap<String, Object> {}

@RestController
@RequestMapping("/system/test")
public class SystemUserController {
    @GetMapping
    public ResponseResult index(@RequestParam MyLinkedHashMap params) {
        return ResponseResult.success();
    }
}

I am using spring boot 2.7. I tried searching for related issues but could not find a solution.
