Unable to inject a RequestScoped bean into a WebSocket server endpoint implementation

Issue

When trying to expose a WebSocket server endpoint which uses an injected RequestScoped bean. It seams that from a WebSocket server endpoint it is not possible to access to the request scope where the managed bean lives.

The exception that has been raised is as follows:

[org.jboss.example.websocket.WebSocketServerEndpoint] and the following error occurred: org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.RequestScoped
