there's an order of magnitude performance cost when using reflection instead of JVM-supported invokedynamic.
Reflection is fine for occasional use (such as loading plugins), but it isn't something you want to use heavily. invokedynamic is of limited use for Java, and is intended for better support of dynamically-typed languages, where EVERY call might be dynamic and the cost of using reflection would be crippling.
