| duke@435 | 25 | // During the development of the JDK 1.4 reflection implementation |
| duke@435 | 26 | // based on dynamic bytecode generation, it was hoped that the bulk of |
| duke@435 | 27 | // the native code for reflection could be removed. Unfortunately |
| duke@435 | 28 | // there is currently a significant cost associated with loading the |
| duke@435 | 29 | // stub classes which impacts startup time. Until this cost can be |
| duke@435 | 30 | // reduced, the JVM entry points JVM_InvokeMethod and |
| duke@435 | 31 | // JVM_NewInstanceFromConstructor are still needed; these and their |
| duke@435 | 32 | // dependents currently constitute the bulk of the native code for |
| duke@435 | 33 | // reflection. If this cost is reduced in the future, the |
| duke@435 | 34 | // NativeMethodAccessorImpl and NativeConstructorAccessorImpl classes |
| duke@435 | 35 | // can be removed from sun.reflect and all of the code guarded by this |
| duke@435 | 36 | // flag removed from the product build. (Non-product builds, |
| duke@435 | 37 | // specifically the "optimized" target, would retain the code so they |
| duke@435 | 38 | // could be dropped into earlier JDKs for comparative benchmarking.) |
