What is libobjenesis-java

libobjenesis-java is:

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.
