Description

Currently for the following code:

interface MyInterface {
    void myMethod()
}
trait MyTrait implements MyInterface {
    @Override void myMethod() { ... }
}

the compiler reports:

Method 'onUrl' from class 'MyTraitTrait$Helper' does not override method from its superclass or interfaces but is annotated with @Override.
 @ line 9, column 5.
       @Override
       ^

1 error

It would make it harder to mismatch a overridden method signature.
