Re: [weld-dev] @ThreadScoped for Weld SE

That's a cool idea. It more or less brings ThreadLocal in line with the CDI scoping mechanism, correct?

I would think this would be useful even in Java EE because you could use it for async threads, I suppose. A specific usage scenario isn't coming to me at the moment. -Dan On Thu, Dec 10, 2009 at 7:45 PM, Peter Royle <howardmoon(a)screamingcoder.com&gt; wrote: Hi, I've implemented ThreadContext and @ThreadScoped (revision 5267) for Weld SE.
