Fix logic error in FirstInChain handling.
Your fix is correct. The current thread may only be registered if not already registered, and if the invoker is not a ContextInitializer (which translates to ci==null)

I don't think we need to be able to change the pathspec, but we need to be able to allow a filter to specify a pathspec so that a filter can be restricted.

Maybe a GluewineFilter that extends Filter, and has a getPath() method? (The same way there is a GluewineServlet).
