                         InvocationTargetException

Convenience method for converting objects without a predefined mapper. This method does not allow objects to be filtered in any way and will inspect every public getter and return its value, if the value is not a Number, String or Date, it will then do the conversion on that object as well. If the return type is a Collection, it will be converted to a JsonArray

Parameters:

o -
