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
