Generation of NestHost and NestMembers attributes using javac?

the specification of NestHost/NestMember attributes is independent of the InnerClass attribute.
The former specifies that there is a private access among the members of the nest the later indicates that the classes comes from the same source files.
For javac currently, a nest member is an inner class of the nest host, so the attributes or more or less aligned, but for other languages than Java this may not be the case and in the future, for Java this may not be the case too. Another example, a JavaEE (like) container may generate proxy classes that are nest members of the proxied class without the proxy being an inner class of the proxied class.
