Namespace-api is set normally in a Servlet Filter, which is normally the beginning point for most application HttpRequests. This means, there is a request coming in, it is serviced by a single-thread. Namespace-api is threadsafe and the namespace is put in the threadlocal, and hence, the same namespace is available during the complete HttpRequest serviced by that thread.
