Please review the webrev at:


LambdaMetafactory is is a quite frequent bootstrap method for
invokedynamic in JDK8.
We can do direct method (LambdaMetafactory) invocation as fastpath when
proved that bootstrap MethodHandle points to LambdaMetafactory.
The modification gives +10% - +35% to lambda linkage performance
(depends on amount of lambdas).

Best regards,
