Please note : Don't delete this thread / post as There is no proper answer available an any of page of StackOverflow. My question is totally different.
I want to mock a private static final field OF A FINAL CLASS
I ahve tried with solution given on How to mock a static final variable using JUnit, EasyMock or PowerMock
static void setFinalStatic(Field field, Object newValue) throws IllegalAccessException, NoSuchFieldException{ field.setAccessible(true);
    // remove final modifier from field
    Field modifiersField = Field.class.getDeclaredField("modifiers");
    modifiersField.setAccessible(true);
    modifiersField.setInt(field, field.getModifiers() & ~Modifier.FINAL);
    field.set(null, newValue);
}
But it is giving me ExceptionInInitializerError at "field.set(null, newValue);"
Please advice
