Disabling the reflection use of direct method handles by adding -Djdk.reflect.useDirectMethodHandle=false allows the microbenchmark to run to completion with only LF interpretation. Possibly there's some latent bug in that reflection code path that cause a circular LF call that is short-circuited when the LF is compiled to bytecode right away.
