Well, one workaround is to use a return type rather than a cast, which is valid, e.g.: | | Cache<Object, Object> myCache = getCache(); | Cache injected; | | private Cache<Object, Object> getCache() | { | return injected; | } | | But that's just an ugly workaround to prevent ugly compiler warnings. One of the things we need to deal with until DI containers start supporting generics better, I suppose (Google Guice has some support for this already).
