Okay, with that I get a different set of COMPILE SKIPPED cases. The non-retryable cases are hard to pin down to any specific benchmark or method in our source as they are reported against java.lang.invoke.LambdaForm$MH. Overall performance is about half the speed, I don't see any catastrophic individual performance cliffs in that, but haven't done a full comparison yet. 65 matches for "COMPILE SKIPPED" in buffer:
