Returns a string which is the name of the class to which a given jobject belongs.
The function jobject-pretty-class-name
returns a string which is the name of the class to which the jobject object belongs. The name is then cached in the jobject.
The class for arrays is "prettified", which means converting it to the way it is declared in Java. For other objects, name is the same as the result of jobject-class-name.
