Will we be forbidding setAccessible(...) calls as well? (such as the one done in datadog.trace.util.MethodHandles#privateFieldSetter(java.lang.Class<?>, java.lang.String))

Sep 18 '25 15:09 nikita-tkachenko-datadog

We won't. Quick quote from my doc about the topic:

But the following will still working:

java.lang.reflect.AccessibleObject#setAccessible(boolean) will work to change the accessibility flag and Field.get() / unreflect() / unreflectGetter() will still allow access to private fields value and method calls.

Going back to draft to carefully evaluate and document each calls. I also envisioned some fixes for some of the calls already.
