This is not an error with json-io.  The JSON you have listed is not any Java 
object, because their is no '@type' tag in the JSON.  Try creating a Bank 
object and then writing one out like this:

Bank bank = new Bank();
String json = JsonWriter.toJson(bank);
System.out.println("bank in Json format");
System.out.println(json);

In order to be abe to cast it directly to an Java class, the JSON must include 
the '@type' tag, or the Json must be an array '[]' in which is can be cast to a 
Object[].

You can read this JSON String into memory like this:

String  jsonString = "{\"name\": \"mybank\",\"address\": \"mybank address\"}";
Map map = JsonReader.jsonToMaps(jsonString);

This this code, you will be able to read in ANY JSON String and then access any 
field of it, by drilling through the Maps.
