Caliper was born partially out of frustration with Japex. It's still early in development. We are currently reviewing every aspect of its methodology with Doug/Josh/Cliff/Brian/et al. With luck, in a few months it will become something very useful for the kinds of microbenchmarks you need to write and run for core-libs work.

If you're someone who lives and breathes Java microbenchmarks, I'd very much like to hear your ideas, off-list.

There is also Japex, a micro-benchmarking framework developed by a Sun group originally for testing XML parsing and Fast Infoset. https://japex.dev.java.net/
