(Similarly as > it does for @RequestScoped, @SessionScoped, ... ) Wouldn't it be a better option to have WebSocket define that scope, using CDI to implement it? That is one possibility, but @UpgradeScoped would be more general than just for WebSocket - it would apply for all HTTP/1.1+ Upgrade applications. In my eyes, it is something which was forgotten to do in Java EE 7 release, since HttpUpgradeHandler was introduced in it. Also please note, that other Servlet related scopes are already in CDI spec, so it seems like it belongs there more than anywhere else. This might have multiple reasons - for example, you can easily define relationship between @UpgradeScoped and others, already existing ones. In this sense, CDI specification now depends on Servlet API (it references some of the classes defined in it), but Servlet does not do that for CDI. I don't think that Servlet spec should introduce similar dependency just because of new scope.
