MethodHandles$Lookup.accessClass does not follow its documentation:
https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/lang/invoke/MethodHandles.Lookup.html#accessClass(java.lang.Class)

Specifically, it throws an exception when accessing an Array Class with a protected inner class as component class when using lookup object with full capabilities
(ie. java.lang.IllegalAccessException: access violation: class [Lp.A$TEST;, from q.B (unnamed module @60215eee)  in the testcase provided)

The expected behavior is accessClass should allow the access and return the passed in class.

Testcase:

package p;

public class A {
    protected enum TEST { ONE }
}



package q;

import p.A;

import java.lang.invoke.MethodHandle;
import java.lang.invoke.MethodHandles;
import java.lang.invoke.MethodType;

public class B extends A {
    public static void main(String[] args) throws Throwable {
        TEST[] arr = new TEST[1];
        Class<?> arrClass = arr.getClass();

        //1) is TEST[] visible
        try {
            MethodHandles.Lookup l = MethodHandles.lookup();
            Class<?> accessClass = l.accessClass(arrClass);
            System.out.println("Passed! accessClass is: "
                               + accessClass.getName());
        } catch (Exception e) {
            System.out.println(e);
        }

        //2) Byte code behaviour with TEST[]
        meth(null);

        //3) MH lookup with TEST[]
        MethodHandle mh = MethodHandles.lookup().findStatic(B.class, "meth", MethodType.methodType(void.class, TEST[].class));
        mh.invoke(null);
    }

    public static void meth(TEST[] arr) {
        System.out.println("called method");
    }
}
