    All of these classes are in `surefire-common` project. Therefor it would be 
nice not to create a new object 
    `new NullConsoleReporter()` but instead keep it as static final constant in 
abstract Factory in surefire-common.
    This would mean that such null-check may be embedded in the factory, e.g. 
`buildConsoleReporter()`. I would say that the caller should pass non-null 
consistent object into this class `TestSetRunListener` via constructor and the 
called class should not make any guess about it (means if == null => guess hide 
the error). If we accepted such paradigm then all such occurrences in this PR 
would have to change it.
