How does annotation injection work, while maintaining security?

How do frameworks inject a resource into a private field without
violating security?

I know how to introspect, and I know how to get annotations, etc. I
just would like to know how to inject something into a private field
for testing purposes.

Another term is "field injection". Most searches are about how to
use. I am looking at how to implement.

Alright I got it....It is a simple case of called setAccessible on a
field in order for that to work.

Field field = t.getClass().getDeclaredField("someField");
field.setAccessible(true);
field.set(t, "woo");
