The existing optimistic fast path can avoid the lock, with the assumption that garbage collection of the cache values are rare. It is fine. However these plain access do require that the cached values to be thread safe and support safe publication.

Given the huge complexity of this cache and confusions around it, I recommend checking out `jdk.internal.util.ReferencedKeyMap`, which is already exported to `java.desktop` module.
