Latest feature `ClassesWithCallbacks` does not work as expected

[masesdevelopers]

Using latest version of JNetReflector it is not possible to obtain the expected result. With the first attempt using android.app.Activity it is possible to highlight that the following configuration snippet

  "ClassesWithCallbacks": [
    {
      "ClassName": "android.app.Activity",
      "Patterns": [
        "on*"
      ]
    }
  ],

fails the generation with:

• Patterns does not work and all methods are created as callbacks then compiling Java side most of the errors reports overridden method is final
• in .NET side all methods are callbacks (implicitly from the previous), but some other information, like fields, are removed
