copy Map<String,Object> cause recursive value

[bljcode]

Are you in the right place?

• For issues or feature requests related to the code in this repository file a Github issue.
• For general technical questions, post a question on Google Groups.

Whats your runtime?

• Dozer version: 6.5.2_
• OS version: macOs 12.5_
• JDK version: 1.8_

Whats the problem?

Steps to reproduce:

public static  void main(String[] args){
       A model = new A();
       LinkedHashMap<String, Object> map = new LinkedHashMap<>();
       map.put("msgExtra",new LinkedHashMap<>());
       model.setTemplateExtendInfo(map);
       Mapper defaultMapper = DozerBeanMapperBuilder.buildDefault();

       B resultModel = defaultMapper.map(model, B.class);

       System.out.println(JSON.toJSONString(resultModel));
   }


   @Data
   public static class A{
       private Map<String, Object> templateExtendInfo = new HashMap<>();

   }
   @Data
   public static  class B{

       private Map<String, Object> templateExtendInfo = new HashMap<>();


   }

run the main method , I find the resultModel.templateExtendInfo recursive value ,templateExtendInfo VALUES: {msgExtra={}} --> {msgExtra=(this Map)}

Observed Results:

What happened? This could be a description, log output, etc.

Expected Results:

What did you expect to happen?
the resultModel.templateExtendInfo has a empty map value

It's a bug of JSON lib. Can not reproduce the sense when use System.out.println(), as shown in screenshots.
