Push upgrade fails due to ContentDocument Trigger for ContentAsset.

If ISV package has ContentAsset, it's possible to fire Apex Trigger, when Partner do push upgrade. Apex Trigger calls Apex Class which is "with sharing", push upgrade might fail. It depends on subscriber's apex trigger and apex class. ISV partner is unable to control subscriber's Apex Trigger and Apex Class. So they are unable to do push upgrade for these subscriber.

This issue occurs by the following behavior

- ContentAsset can be included to ISV package.
- ContentDocument/ContentVersion trigger is fired when ContentAsset is deployed


- Ordered steps to reproduce in a fresh org

1. sign up dev org

Object Name: w3873619
4. Create a packge
4-1. Set a namespace prefix
Namespace Prefix: w3873619ns
4-2. Create a package
Package Name: w3873619pac
Managed: checked
5. add created custom object to package.
6. upload this package with released version(version1)
7. enable "Lightning Experience"
8. switch to LEX
9. Create Lightning App

App Name: w3873619
Developer Name: w3873619
Upload Image: "everything OK"
9-2. Save
10. switch to Salesforce Classic
11. add created Lightning App to package
12. upload this package with released version(version2)

3. Create a custom object
Label: obj
Object Name: obj
4. Create a custom field for created custom object
Data Type: text
Field Label: text

Field Name: text
5. create apex trigger and apex class for ContentDocument

Apex Trigger
trigger ContentDocumentTrigger on ContentDocument (after insert) {
ContentDocumentTriggerHandler c = new ContentDocumentTriggerHandler();

Apex Class
public with sharing class ContentDocumentTriggerHandler{
public void execute(List<ContentDocument> cds){
for( ContentDocument c : cds ){
obj__c o = [ select Id, text__c from obj__c where text__c = :c.Id ];

1. push upgrade package to version2 from version1

>> push upgrade fails.

- Disable Apex Trigger on subscriber org
- Update Apex Class to "without sharing" from "with sharing"

Is it Fixed?
