| * Description |
| * The test verifies that JVM prints tiered events with -XX:+PrintTieredEvents |
| * for tiered compilation explicitly enabled with -XX:+TieredCompilation. |
| * If tiered compilation is explicitly disabled the test verifies that there are no |
| * output from PrintTieredEvents. |
