I change the way the properties are collected using the Class.getMethods() api instead iterating the class hierarchy using Class.declaredMethods(). I think that collect the properties using the getMethods api should be a better approach because:

• it returns all public methods considering both super classes and interfaces
• there's no need to filter public methods
• there's no need to iterate through the class hierarchy

Moreover, in this way the properties declared in the interfaces will not be ignored.

Check List:

• Fixes Recursion comparison using properties ignores default interface methods. #3125 (ignore if not applicable)
• Unit tests : YES
• Javadoc with a code example (on API only) : YES
• PR meets the contributing guidelines
