      Description

      Hotspot patch [1] introduces a test case
      hotspot/test/compiler/interpreter/DisableOSRTest.java which also
      exposes the same issue on aarch64.

      I.e. with -XX:-UseOnStackReplacement and -XX:+TieredCompilation
      options, there are still OSR compilations found from
      -XX:+PrintCompilation.
