While `{@inheritDoc CharSequence}` does work very well for `StringBuilder` and `StringBuffer` (via `AbstractStringBuilder` to shorten code size), it simply doesn't have *any* effect when applied at `String`: `make docs` successfully finishes without warnings or errors, but `String.html` still contains just the link to `CharSequence` but *is missing* the copy of the JavaDoc main text. I simply do not see why. Any ideas? 🤔

Unfortunately the same happens. 🙁
