    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.)
