Thanks a lot for your quick answer.
I found an issue in my Spring injection which is now fixed. Alfresco services are now usable in my separate thread, but I'm facing
a new issue that I just don't understand, when trying to set aspect recursively.
Do you have any idea/advice ?

thanks.

Thanks a lot for your quick answer. You're right, I missed something when injecting alfresco services.
