The `Lookup` object produced by `MethodHandles::privateLookupIn` in this release might not have full privilege access. A `Lookup` that possesses both PRIVATE and MODULE access modes is said to possess full privilege access that can be tested with the `Lookup::hasFullPrivilegeAccess` method.
In previous releases, a `Lookup` returned from `MethodHandles::privateLookupIn` could be used to look up caller-sensitive methods. In Java SE 14, if a `Lookup` does not have full privilege access (even though it has private access mode), it might fail to look up caller-sensitive methods.
