[SOLVED] the JAR of this class file belongs to container 'Junit 4' which does not allow modifications to source attachements on its entries

I am new to Junit framework. I am trying to invoke private method in another class from Junit test class using reflection API. I am getting below error while running JUnit test:

When I am debugging the application I do see the following:

the JAR of this class file belongs to container 'Junit 4' which does not allow modifications to source attachements on its entries.
