I'll note that replacing a lambda with an anonymous class has a very marginal effect on startup when amortizing the cost of setting up the infrastructure for spinning classes. What can have a decent effect is if we can replace a few lambdas/anon classes with more imperative code that spins up/loads fewer classes, e.g., desugaring streams to for loops. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/17108#discussion_r1644202229
