One additional comment:
The lookup access has been extended since 14 to include `MODULE` and `ORIGINAL`
access.
`Lookup::hasFullPrivilegeAccess` returns true if the lookup has `PRIVATE` and
`MODULE` which means that this lookup is not teleported from another module via
`Lookup::in` and `MethodHandles::privateLookupIn`.
What privilege do you expect the `caller` lookup should have? I believe full
privilege access is the appropriate privilege. The `ORIGINAL` access is
stricter as the lookup must be created from the original lookup class.
[1] shows what access a `Lookup` has when being produced via different APIs.
