There appears to be some confusion here. My webrev REMOVES
sun.reflect.Reflection completely, since getCallerClass(int) was its
last method. For compilation purposes, the test uses a patched
jdk.unsupported module with sun.reflect.Reflection, but that class
is not present at runtime. So the sun.reflect.Reflection internal API
has been removed, no?

There is no other API in sun.reflect.Reflection, unless you mean
to use something in sun.reflect.ReflectionFactory ?

That’s what the test now does with my changes. Why separate it
out into a separate issue?   If we need a test for an internal API, I
can add a scenario that uses sun.reflect.ReflectionFactory.
