This will never happen. `jdk.internal.reflect` is a non-exported package in
`java.base` module. If another module `M` defines a class whose superclass is
in `jdk.internal.reflect` package, `java.base` must export
`jdk.internal.reflect` package to `M` for access. Otherwise, it will fail the
super access check, as done in the check below this deleted code.
Reflection::VerifyClassAccessResults vca_result =
Reflection::verify_class_access(this_klass, InstanceKlass::cast(super),
false);
