The test doesn't fail with -Xmixed and -XX:+TieredCompilation, but reliably fails both with -XX:-TieredCompilation or -XX:+TieredCompilation -XX:TieredStopAtLevel=1. The failure mode is slightly different though: with C2 it fails on frame #3 and with C1 it fails on frame #4.

Diagnostic output:
  -XX:-TieredCompilation:
