| 25 // During the development of the JDK 1.4 reflection implementation | |
| 26 // based on dynamic bytecode generation, it was hoped that the bulk of | |
| 27 // the native code for reflection could be removed. Unfortunately | |
| 28 // there is currently a significant cost associated with loading the | |
| 29 // stub classes which impacts startup time. Until this cost can be | |
| 30 // reduced, the JVM entry points JVM_InvokeMethod and | |
| 31 // JVM_NewInstanceFromConstructor are still needed; these and their | |
| 32 // dependents currently constitute the bulk of the native code for | |
| 33 // reflection. If this cost is reduced in the future, the | |
| 34 // NativeMethodAccessorImpl and NativeConstructorAccessorImpl classes | |
| 35 // can be removed from sun.reflect and all of the code guarded by this | |
| 36 // flag removed from the product build. (Non-product builds, | |
| 37 // specifically the "optimized" target, would retain the code so they | |
| 38 // could be dropped into earlier JDKs for comparative benchmarking.) | |
