---------------------------------------------------------------
I fixed #1 in Bootique
(https://github.com/bootique/bootique-cayenne/tree/master/bootique-cayenne-jcache/src/main/java/io/bootique/cayenne/jcache/cache).
This solution can be ported to Cayenne. The beauty of it is that it is
backwards compatible in a sense that the code outside Cayenne can now place
entries in the same caches as Cayenne and they will get invalidated (as well as
their own untyped caches). #2 above is just icing on the cake solving a problem
with strictly typed caches and is not strictly required.

> QueryCache: support for referencing type-safe caches

> Key: CAY-2259
> URL: https://issues.apache.org/jira/browse/CAY-2259
> Project: Cayenne
> Issue Type: Task
> Affects Versions: 4.0.M5
> Reporter: Andrus Adamchik
> Assignee: Andrus Adamchik
>
> With cayenne-jcache we lost the ability to invalidate caches not handled by
> Cayenne. The API for CacheManager's caches introspection requires the caller
> to know the generic parameters of a named cache. So we can no longer
> invalidate caches that were not created for Cayenne (and that are known to be
> of type "Cache<String, List>").
> A few changes to address this:
> 1. Internally use "untyped" caches for storage. This would allow the same
> caches to be reused by the code outside Cayenne.
> 2. Add API to QueryCache to handle invalidation of typed caches with known
> key and value types. Extend @CacheGroups annotation to specify cache generics
> "signatures", add support for it in CacheInvalidationFilter.
