Summary
Create a managed package released version with 1.0, and it contains a global class with no constructor defined.You install the managed package into a subscriber org and create a custom class that instantiates an instance of the global class from the package.Then back in the managed package packaging org, add an explicit global constructor to the global class, and release version 1.1 of the package.After installing the latest version (1.1) in the subscriber org, try to change the manage package api version of the apex class to 1.0 and we will see "Package Visibility: Constructor is not visible: [testns.RegularClass].<Constructor>() ".

Repro
a) Create a managed package with the following classes:

global with sharing class RegularClass {
}

Test class:

@isTest
private class TestClass {
@isTest
private static void test() {
RegularClass r = new RegularClass();
}
}

b) Upload version 1.0 of the managed package
c) Install the managed package into another org, which will be called the subscriber org
d) In the subscriber org, add the following class (replace 'testns' with the appropriate namespace)

public with sharing class MyCustomClass {
public MyCustomClass() {
testns.RegularClass b = new testns.RegularClass();
}
}

e) Go back to the managed package packaging org, and change RegularClass to the following

global with sharing class RegularClass {
global RegularClass() {
}
}

f) Upload version 1.1 of the managed package
g) Install version 1.1 of the package into the subscriber org
h) Go To 'MyCustomClass' and change the manage package version to 1.0
i) Receive the following error:
Package Visibility: Constructor is not visible: [testns.RegularClass].<Constructor>()

Workaround
Set API version 1.1 of the managed package to avoid getting the error.

Salesforce team has created the document bug to update in our documentation regarding this behavior.

Is it Fixed?
