> It appears that validation of configuration properties is performed in the 
> ConsumerConfig and ProducerConfig constructors. This is generally bad 
> practice as it couples object construction and validation. It also makes it 
> difficult to mock these objects in unit tests. 
> Ideally validation of the configuration properties should be separated from 
> object construction and initiated by those that rely/use these config objects.
