Seems jenkins did manage to come back by itself, after 20 minutes.<br>
<br>
The good news is that it seems that after 3 days of work, we found a<br>
way (minus some ansible hack to be fixed) to dynamically add builders.<br>
The bad new is that jenkins reload is busted, cause 20 minutes of<br>
downtime do not seems optimal at all, and we would need to fix that<br>
before going on.<br>
<br>
For folks who are eager on reading java, that's somewhere here:<br>

( from ./core/src/main/java/hudson/cli/ReloadConfigurationCommand.java<br>
to doReload, to reload to loadTasks).<br>
