> Please review this change that adds a new dynamic proxies implementation as > hidden classes. > > Summary: > 1. Adds new implementation which can be `-Djdk.reflect.useHiddenProxy=true` > for early adoption. > 2. ClassLoader.defineClass0 takes a ClassLoader instance but discards it in > native code; I updated native code to reuse that ClassLoader for Proxy > support. > 3. ProxyGenerator changes mainly involve using Class data to pass Method list > (accessed in a single condy) and removal of obsolete setup code generation. > > Comment: Since #8278, Proxy has been converted to ClassFile API, and > infrastructure has changed; now, the migration to hidden classes is much > cleaner and has less impact, such as preserving ProtectionDomain and dynamic > module without "anchor classes", and avoiding java.lang.invoke package.
