I plan to commit this on monday.
[~tucu00], Please let me know if you found any specification which prevents sharing filter
instances across webapps.

> The HttpServer2.defineFilter creates a Filter instance for each context. By default,
there are 3 contexts.
> So there will be 3 separate AuthenticationFilter instances and corresponding AuthenticationHandler
instances. This also results in 3 separate initializations of AuthenticationHandler.
> The log file illustrating this repeated initialization is attached.
