| * DESCRIPTION |
| * The test tries to detect a stale handle in VolatileCallSite due to store-after-load reordering in |
| * modern CPU. |
| * The current Oracle Hotspot JVM implementation uses an internal mutex when relinking a call site, |
| * which serves as memory barrier between store and load in this test, so I never saw it failing. |
