/**
 * The MutableInteger class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int.
 * This class is used because Java.Lang.Integer objects are defined as Imutable. Yet, we need to maintain object reference when it's passed to the JNI library using.
 * So, we defined a simple Class which extends Java.Lang.Object to resolve the problematic.
