>> As a follow-up to #6375, this change refactors java.io.ObjectInputStream.Caches#subclassAudits and java.io.ObjectOutputStream.Caches#subclassAudits to use ClassValue instead of SoftReference, similar to what we did in #6375 for java.io.ObjectStreamClass.Caches#localDescs. Then we can now also remove the common machinery java.io.ObjectStreamClass#processQueue and java.io.ObjectStreamClass.WeakClassKey.
