/**
 * @assertion String convert(Object o)
 * If the conversion throws, or returns a value that is not directly
 * serializable, a JsonUnsupportedObjectError exception is thrown. If the call
 * throws, the error is caught and stored in the JsonUnsupportedObjectError's
 * cause field.

 * If a List or Map contains a reference to itself, directly or through other
 * lists or maps, it cannot be serialized and a JsonCyclicError is thrown.

 * Json Objects should not change during serialization.
 * If an object is serialized more than once, stringify is allowed to cache the
 * JSON text for it. I.e., if an object changes after it is first serialized,
 * the new values may or may not be reflected in the result.
 
 * @description Checks that if the object does not support "toJson()" method,
 * then an exception is thrown
