Summary: Instantiate New Object

Description: 

Java already supports this dynamic instantiation of classes
using Class.newInstance(). However, this only works if the
class has an appropriate constructor. There are many times
when a class cannot be instantiated this way, such as when
the class contains:
* Constructors that require arguments.
* Constructors that have side effects.
* Constructors that throw exceptions.
As a result, it is common to see restrictions in libraries
stating that classes must require a default constructor.
Objenesis aims to overcomes these restrictions by bypassing
the constructor on object instantiation.
Needing to instantiate an object without calling the
constructor is a fairly specialized task, however there
are certain cases when this is useful:
* Serialization, Remoting and Persistence -
  Objects need to be instantiated and restored to a
  specific state, without invoking code.
* Proxies, AOP Libraries and Mock Objects - Classes can be
  subclassed without needing to worry about the super()
  constructor.
* Container Frameworks - Objects can be dynamically
  instantatiated in non-standard ways.
