What happened to Java's @OverridingMethodMustCallSuper?

Question

Did I dream this? I could have swore I read something about java 7 supplying an annotation that you could place on a method to ensure all subclasses call super. Has this been renamed, or dropped, or was it never actually considered?

Answer 1

It was part of JSR 305: Annotations for Software Defect Detection and called @OverridingMethodsMustInvokeSuper.

The JSR is inactive, but a reference implementation is available bundled with FindBugs

Answer 2

It could have been suggested for project Coin, which accepted many suggested but picked the best/simplest of the list.

You can do this instead.

public final void method() {
     // super code
     subClassMethod();
}

protected void subClassMethod() {
    // can be overridden.
}
