Step to reproduce:
- try to open: http://localhost:8080/camunda/app/cockpit/default, http://localhost:8080/camunda/app/admin/default or http://localhost:8080/camunda/app/tasklist/default
- the webapp does not load and no messages are shown
- the webapp loads (and starts)
After digging a bit I found out that the problem comes from the URL.
If the URLs above were ending with "/", the webapps load correctly otherwise, the scripts cannot determine which "engine" is used.
