    28 // During the development of the JDK 1.4 reflection implementation

    29 // based on dynamic bytecode generation, it was hoped that the bulk of

    30 // the native code for reflection could be removed. 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.)
