Objenesis is a small java library that serves one purpose: to instantiate a new object of a particular class. 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.
