Does caffeine loading cache do automatic interning of cached values?

Hi we're creating a LoadingCache with caffeine with - (1) maxSize (2) variable expiration w/ its builder.
Can caffeine intern cached values automatically (i ask this since i'm debugging an issue and want to eliminate this as a root cause).
At the moment we don't use external interning mechanisms for either keys or values - also the cacheloader always creates new objects (never reuses or returns static objects).

No, nothing magical like that. You can think of it as a ConcurrentHashMap with an automatic removal policy. The entries are shared until evicted, loaded if not found, etc. It does not try to keep them around any longer, e.g. by calling String.intern. It doesn't copy objects into or out of the map, etc. It should be boring and feel similar to the core Java collections.

(We do offer an Interner for those who want that behavior)
