[jira] [Created] (WICKET-5252) PropertyResolver breaks immutable objects by calling setAccessible

Daniel Zwicker created WICKET-5252:
--------------------------------------

             Summary: PropertyResolver breaks immutable objects by calling setAccessible
                 Key: WICKET-5252
                 URL: https://issues.apache.org/jira/browse/WICKET-5252
             Project: Wicket
          Issue Type: Bug
    Affects Versions: 6.8.0
            Reporter: Daniel Zwicker


If a Bean only have private fields and no setter this object is immutable. The decision to implement such an object has a bunch of implications. e.g. it is thread safe, you can take snapshots of these object to store a version history and so on.

Now your use of reflection breaks this isolation silently. I believe if somebody want set the values of the object he should implement a setter or provide a public field.
