Unfortunately 31 // there is currently a significant cost associated with loading the 32 // stub classes which impacts startup time. Until this cost can be 33 // reduced, the JVM entry points JVM_InvokeMethod and 34 // JVM_NewInstanceFromConstructor are still needed; these and their 35 // dependents currently constitute the bulk of the native code for 36 // reflection. If this cost is reduced in the future, the 37 // NativeMethodAccessorImpl and NativeConstructorAccessorImpl classes 38 // can be removed from sun.reflect and all of the code guarded by this 39 // flag removed from the product build. (Non-product builds, 40 // specifically the "optimized" target, would retain the code so they 41 // could be dropped into earlier JDKs for comparative benchmarking.) 42 43 //#ifndef PRODUCT 44 # define SUPPORT_OLD_REFLECTION 45 //#endif 46 47 #endif // SHARE_VM_RUNTIME_REFLECTIONCOMPAT_HPP
