JDK-8277072 - ObjectStreamClass caches keep ClassLoaders alive
Description
As a follow-up to JDK-8277072, we should refactor java.io.ObjectInputStream.Caches#subclassAudits and java.io.ObjectOutputStream.Caches#subclassAudits to use ClassValue instead of SoftReference, similar to what we did in JDK-8277072 for java.io.ObjectStreamClass.Caches#localDescs. Then we can also remove the common machinery java.io.ObjectStreamClass#processQueue and java.io.ObjectStreamClass.WeakClassKey.
Comments
Fix-request (jdk18u): The change fixes a small memory leak, similar and related to JDK-8277072. The original change has baked for some weeks in JDK19 and applies cleanly. tier1-3 are passing fine.
