Lazy underriding doesn't work

[aviv-nd]

When configuring underrideToString = "underrideToString" and defining the following:

public interface Example {
    @Lazy
    default String underrideToString() {
        ...
    }
}

This is generated in the immutable class:

  @Override
  public String toString() {
    return Url.super.underrideToString();
  }

And the method executes every time instead of lazily.

The lazy implementation for underrideToString is also generated, so it would be great if it were used.
