/**
 * Instantiates an object, WITHOUT calling it's constructor, using internal
 * sun.reflect.ReflectionFactory - a class only available on JDK's that use Sun's 1.4 (or later)
 * Java implementation. This is the best way to instantiate an object without any side effects
 * caused by the constructor - however it is not available on every platform.
