Unfortunately // there is currently a significant cost associated with loading the // stub classes which impacts startup time. Until this cost can be // reduced, the JVM entry points JVM_InvokeMethod and // JVM_NewInstanceFromConstructor are still needed; these and their // dependents currently constitute the bulk of the native code for // reflection. If this cost is reduced in the future, the // NativeMethodAccessorImpl and NativeConstructorAccessorImpl classes // can be removed from sun.reflect and all of the code guarded by this // flag removed from the product build. (Non-product builds, // specifically the "optimized" target, would retain the code so they // could be dropped into earlier JDKs for comparative benchmarking.) //#ifndef PRODUCT # define SUPPORT_OLD_REFLECTION //#endif
