Re: [Resteasy-users] Problem with resteasy test application

Which threading model are you using. I got the error you are seeing once 
with the Singleton model but when I moved to the per request model for 
my resources the error went away. I'm afraid that I was unable to track 
down why the Singleton model wasn't working.
