    Check that a bridge only overrides members that are also overridden by the original member.

    Check that a bridge only overrides members that are also overridden by the original member.

    That is, check that the signature of the bridge method does not accidentally override some other method, possibly written by the user or inherited.

    As an optimization, only perform this check for susceptible bridges.

    This test is necessary for members that have a value class in their type. Such members are special because their types after erasure and after post-erasure differ. This means we generate them after erasure, but the post-erasure transform might introduce a name clash. The present method guards against these name clashes.

    A bridge might also introduce a signature that accidentally matches an existing method. In that case, it will have a parameter erased to the upper bound of a type parameter in the signature of the member overridden by the original member. (That upper bound might be `Object`.) By contrast, erasure of a parameter `List[A]` would already have induced an error if there were a matching member.

    member

      The original member

    other

### Deprecated Value Members

   Annotations
     @deprecated @inline()
   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.

     (Since version 2.13.0) Use `->` instead. If you still wish to display it as one character, consider using a font with programming ligatures such as Fira Code.
