* VM Testbase keywords: [feature_mlvm, nonconcurrent]
* VM Testbase readme:
* 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.
