On the one hand yes, on the other hand Java also generates Bridge methods when you implement a generic interface. A MyType implementing Comparable<MyType> will contain a compareTo( MyType ) method and a generated compareTo( Comparable ) bridge method. It is more likely that generated classes, countless getters and setters and a tendency to small methods has a higher impact.
