For cases that are not a loadable class name or not a type descriptor, the spec of `Class::forName` and `MethodType::fromMethodDescriptorString` should specify clearly. If not, we should clarify those specs rather than explaining the negative cases in the api note. I think these API specs can be improved especially `forName` doesn't talk about the name for array type which is a fully-qualified name. I'll create a PR for that and see if that helps the clarification. ------------- PR Comment: https://git.openjdk.org/jdk/pull/14411#issuecomment-1595179872
