#863 CloneMethodMustImplementClonable and inherited cloneable

[Sascha Kiedrowski]

Assume the following code

public class MyDateFormat extends SimpleDateFormat {
@Override
public final Object clone() {
final Object clone = super.clone();
// special clone handling
return clone;
}
}

By extending SimpleDateFormat, the Clonable interface is in the "implements" List.

Nevertheless PMD gives me the warning CloneMethodMustImplementCloneable. It seems that only the implements List of the class itself is checked.
