> The @PreDestoy method called look like this :
> ```
> for ( String mbean : mbeans) {
>     unregister(mbean);
>     mbeans.remove(mbean);
> }
> ```
> Causing mbeans being ignored and not unregistered.
> Solution is to simply not modify collection content while working on it and simply clear it outside the for loop.
> Acceptance criteria :
>  - Being able to launch a James server, stop it and restart it.
