NPE during ear deployment

Hi the list,

I'm trying to move an application from Jonas 4 to Jonas 5.2.1.
I got this error message and I'm not sure where to look.

The application.xml looks correct.

Any idea ?

Thanks.

PS : I did try to post my question by email but apparently it still not there
after 45 min. I hope I won't post it twice.
