Infinite redirect loop when deploying Java WAR to Heroku via add-on

When my Bamboo build job deploys my Java WAR file to Heroku and I try to access it, Chrome/Firefox etc all end up giving me a redirect loop error:

The webpage at https://myapp.herokuapp.com/ has resulted in too many redirects.

However, when I deploy the exact same Java app via my command line directly to Heroku (git push heroku master), it all works fine.

I realise this probably has something to do with the difference between deploying a pre-built WAR file and having Heroku build the WAR file from its own git repo. The thing is, I don't know what I need to change to get the pre-built WAR to work.

These are the steps I took:

I built and deployed my app following this tutorial: https://devcenter.heroku.com/articles/spring-mvc-hibernate which worked fine and deployed my app without any issues.

I then decided that I wanted to use Bamboo to build and deploy the application, instead of me having to manually push every change to Heroku, so I set up Bamboo with the following tasks:

1. Source Code Checkout from Bitbucket
2. Build WAR via Maven
3. Heroku deploy WAR artifact

This doesn't work, and results in the infinite redirect issue.

Ok, looks like this has to do with SSL and my security-constraint definition in my web.xml. I need to do some more investigation on how to get SSL working on Heroku...
