I'll do that. What I did before was run tiers1 - 3 with -XX:DeoptimizeALot -XX:+VerifyStack. That's how I found runtime/BootstrapMethod/BSMCalledTwice.java as a reproducer. Unfortunately, running all tests with both flags finds too many other problems, and running with -XX:DeoptimizeALot but not -XX:+VerifyStack may give mysterious crashes instead of a nice assert if it finds a problem.
