When a superclass (e.g. 'Bar') has protected abstract methods and an unresolved import (that doesn't otherwise cause any compiler errors), the overridden methods in the sub-class get a compiler error "Cannot reduce the visibility of the inherited method from Bar", which is quite misleading.

It seems that in this situation, all abstract methods in the superclass get compiled as 'public' regardless of their actual declared visibility.  This can be observed by running code similar to the following:
System.out.println(Modifier.isPublic(Bar.class.getDeclaredMethods()[0].getModifiers()));
 

Reproducible: Always

Steps to Reproduce:
1. Create a superclass with a compilation error:
package example;
import invalid.type.Name;  // only error
public abstract class Bar {
    protected abstract boolean isBaz(); 
}

2. Create a subclass:
package example;
public class Foo extends Bar {
	protected boolean isBaz() {
		return false;
	}
}

3. Build project and observe unexpected compiler error on Foo.isBaz().
