Crash Nuxeo CMF if 2 cases have complex metadata with the same name

For a CMF Studio project, if 2 cases have a complex type metadata with the same name in their specific schema, it makes the application crashes at startup (both after a update center and a manual deployment).
The login page shows up but it is impossible to connect (web browser fires a "Cette page Web présente une boucle de redirection." exception).
Could not reproduce in a DM project.
Could not reproduce with other type of metadata, they have to be "complex".

Jar, logs and studio project to be attached
