I studied your code and we are fundamentally in agreement!
... Except for need for periodic cleanup of the cache...
Maybe we should do
CompletableFuture.runAsync(purgeCache,
CompletableFuture.delayedExecutor(1, SECONDS))
as a periodic task while cache is non-empty instead of my strategy of
relying on a weak reference.

Purging a cache on quiescence in the optimal way seems to be a hard problem.
Time to write ObjectPool<T> (as many others have done before us)?

ObjectPool(Supplier<T> factory,  Consumer<T> releaser, maxCacheSize,
keepAliveTime)

Except this time we'll do it right!  With jdk9 machinery!
