Ivo Ladage - van Doorn commented on AMDATU-82:
----------------------------------------------
I'm using the FutureTask mechanism since this provides an easy way to implement
a caching mechanism with minimal lock contention. Instead of synchronizing on
this or a whole map, in this approach threads are only blocked when requesting
an uncached URL and requesting the gadgetspec for a certain URL is guaranteed
to happen only once.
Regarding separation of concerns; I agree that by design it would be better to
separate caching logic from the service implementation. However, I think we
should come up with a generic design pattern used by all cached services. I'll
create a separate issue for it.
