1. package access class with public constructor

package hiding.packageaccess;

class PublicConstructor {
  public PublicConstructor() {}
}

2. access public construtor above

// hiding/CreatePackageAccessObject.java
// (c)2017 MindView LLC: see Copyright.txt

// {WillNotCompile}

import hiding.packageaccess.*;

public class CreatePackageAccessObject {
  public static void main(String[] args) {
    new PublicConstructor();// compile error
  }
}

my compiler error message:

CreatePackageAccessObject.java:7: error: package hiding.packageaccess does not exist
import hiding.packageaccess.*;
^
CreatePackageAccessObject.java:11: error: cannot access PublicConstructor
    new PublicConstructor();
        ^
  bad source file: ./packageaccess/PublicConstructor.java
    file does not contain class PublicConstructor
    Please remove or make sure it appears in the correct subdirectory of the sourcepath.
2 errors

Summary, declaring a constructor public inside a packageaccess class doesn't actually make it public, and it should probably be flagged with a compiler error at the point of declaration.
