reads fine to me. You could specify the context to refer to servlet context, but that might not be necessary.

@volosied does this look better to you? I pushed up a change that uses ServletContext:

log.log(Level.INFO, "f:websocket support is enabled but the WebSocket ServerContainer instance " + "cannot be found in the current ServletContext.");

looks good, thanks!
