> > It looks like the request is to use a weak cache for the static `ALL` field so that instances may be collected when there are no strong references held by the application. As this is a static field that can be called by multiple threads, it should also be thread-safe. It doesn't look like ordering matters, so you could use a Caffeine weakKey cache with `Collections.newSetFromMap`. Something like, > > ```java > > private static final Set<MemorySafeWindowTinyLFUMap<?, ?>> ALL = Collections.newSetFromMap( > > Caffeine.newBuilder().weakKeys().<MemorySafeWindowTinyLFUMap<?, ?>>build().asMap()); > > ``` > > as I know, Caffeine cannot be memory safe, or catch Out Of Memory Error to release caffeine cache. -- This is an automated message from the Apache Git Service.
