[weld-dev] Two interceptor bindings considered the same when the only annotation member is nonbinding?

[Marko Lukša]

As Jozef pointed out, this has been clarified in 1.1. So what should I 
do in 1.0, since in 1.0 there is nothing that says that interceptor 
bindings on methods override the bindings of the class.

As I wrote below, it is probably perfectly legal to have the same 
binding on both the class and the method. But since 
BeanManager.resolveInterceptors is supposed to throw an exception if you 
pass two instances of the same binding, weld should make sure it calls 
resolveInterceptors with only one instance (the method's as in 1.1).
