The following text contains a user issue (in <issue/> brackets) posted at a repository. Further, you are provided with file contents of several files in the repository that contain relevant code (in <code> brackets). It may be necessary to use code from third party dependencies or files not contained in the attached documents however. Your task is to identify the issue and implement a test case that verifies a proposed solution to this issue. More details at the end of this text.

      Hi, I've tried the code below to serialize properties that have both a getter and a setter. However the output is: `{"readonly":1,"readwrite":2}` while I expected it to be: `{"readwrite":2}`.

``` java
public class Main {

    public static class DataB {
        private int readonly;
        private int readwrite;

        public DataB() {
            readonly = 1;
            readwrite = 2;
        }

        public int getReadwrite() {
            return readwrite;
        }
        public void setReadwrite(int readwrite) {
            this.readwrite = readwrite;
        }
        public int getReadonly() {
            return readonly;
        }
    }

    public static void main(String[] args) {
        ObjectMapper mapper = new ObjectMapper(); 
        mapper.setVisibility(PropertyAccessor.ALL, Visibility.NONE);
        mapper.setVisibility(PropertyAccessor.GETTER, Visibility.PUBLIC_ONLY);
        mapper.setVisibility(PropertyAccessor.SETTER, Visibility.PUBLIC_ONLY);
        mapper.enable(MapperFeature.REQUIRE_SETTERS_FOR_GETTERS);
        DataB dataB = new DataB();
        try {
            String json = mapper.writeValueAsString(dataB);
            System.out.println(json);
        } catch (JsonProcessingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}
```

Please generate test cases that check whether an implemented solution resolves the issue of the user (at the top, within <issue/> brackets).
You may apply changes to several files.
Apply as much reasoning as you please and see necessary.
Make sure to implement only test cases and don't try to fix the issue itself.
You are not allowed to read git history.
