Trying to upgrade XWiki from 11.0.3 to 11.1

Docker on Ubuntu.

My yml file:

version: '2'
networks:
  bridge:
    driver: bridge
services:
  web:
    # Use an already built XWiki image from DockerHub.
    image: "xwiki:11.1-postgres-tomcat"
    container_name: xwiki-postgres-tomcat-web
    depends_on:
      - db
    ports:
      - "8080:8080"
    # The DB_USER/DB_PASSWORD/DB_HOST variables are used in the hibernate.cfg.xml file.
    environment:
      - DB_USER=xwiki
      - DB_PASSWORD=XXXXXX
      - DB_DATABASE=xwiki
      - DB_HOST=xwiki-postgres-db
    # Provide a name instead of an auto-generated id for the xwiki permanent directory configured in the Dockerfile,
    # to make it simpler to identify in 'docker volume ls'.
    volumes:
      - xwiki-data:/usr/local/xwiki
    networks:
      - bridge
  # The container that runs PostgreSQL
  db:
    image: "postgres:9.5"
    container_name: xwiki-postgres-db
    volumes:
      - postgres-data:/var/lib/postgresql/data
    environment:
      - POSTGRES_ROOT_PASSWORD=XXXXXX
      - POSTGRES_PASSWORD=XXXXXX
      - POSTGRES_USER=xwiki
      - POSTGRES_DB=xwiki
      - POSTGRES_INITDB_ARGS="--encoding=UTF8"
    networks:
      - bridge
volumes:
  postgres-data: {}
  xwiki-data: {}

But, after I do a docker-compose up -d, I get the following in a browser:

HTTP Status 500 – Internal Server Error

Type Exception Report

Message com.xpn.xwiki.XWikiException: Error number 11007 in 0: Failed to extract Entity Resource Reference from URL [http://my.domain.com/bin/distribution/XWiki/Distribution?xredirect=%2Fbin%2Fview%2FMain%2F]

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

Exception

javax.servlet.ServletException: com.xpn.xwiki.XWikiException: Error number 11007 in 0: Failed to extract Entity Resource Reference from URL

I also see this error in the docker logs:

Root error: [MappingNotFoundException: resource: activitystream.hbm.xml not found]

Hi, see the release notes for https://www.xwiki.org/xwiki/bin/view/ReleaseNotes/Data/XWiki/11.1/#HIntroductionoftheEventStreamStore

I suspect this is going to affect a lot of users unfortunately…

PS: The RN for 11.1 was missing the info. It was in the RN for 11.1RC1. I just fixed the RN for 11.1
