Hi David,

I suspected the adding of src/java.base/share/classes/java/io/ClassCache.java and the usage of it, would mean this patch would have to go through the "proving ground" of valhalla. I am happy to resubmit to core-libs-dev if that is not the case or I have misunderstood. Ben I don't have the full context here but core-libs-dev is the place to bring optimizations to serialization. As David said, serialization and OIS/deserialization in particular, has a long rap sheet, including security issues found with previous attempts to cache the "latest user defined class loader". I also have concerns that this is introducing code that may not be exercised in OpenJDK. If you can get someone to publish a webrev on cr.ojn and start a discussion on core-libs-dev then it would be helpful.
