Description

Example:

package one;
public class Base {
    protected int foo() {
        123
    }
}

package two;
class SubBase extends Base {
    class Inner {
        int test() {
            foo()
        }
    }
    
    int innerTest() {
        new Inner().test()
    }
}
assert new SubBase().innerTest() == 123

The code above will fail with the following error:

java.lang.IllegalAccessError: tried to access method one.Base.foo()I from class two.SubBase$Inner

This is due to bridge methods for protected methods not being correctly generated (and subsequently used when writing protected method invocations.)
