<h3>Known Limitations</h3>
<h4>Accessing Public Constructors In A Default Access Superclass</h4>
<p>There is an issue when invoking public constructors contained in a default access superclass.
Reflection locates these constructors fine and correctly assigns them as public.
However, an <code>IllegalAccessException</code> is thrown if the constructors is invoked.</p>
<p><code>ConstructorUtils</code> contains a workaround for this situation.
It will attempt to call <code>setAccessible</code> on this constructor.
If this call succeeds, then the method can be invoked as normal.
This call will only succeed when the application has sufficient security privilages.
If this call fails then a warning will be logged and the method may fail.</p></div>
