    Description

      (This RFE is in need of a better name, when I know exactly what can or cannot be done ....)

      Resolution of dynamic bytecodes such as invokedynamic and invokehandle requires the creation of many objects such as LambdaForm, MethodType, MethodHandle, etc. Also, in many cases, LambdaForm${MH,DMH} classes are generated dynamically.

      The goal is this RFE is to improve start-up time by generate all these resolution artifacts ahead-of-time during CDS archive creation.
