-/**
- * A {@code VolatileCallSite} is a {@link CallSite} whose target acts like a volatile variable.
- * An {@code invokedynamic} instruction linked to a {@code VolatileCallSite} sees updates
- * to its call site target immediately, even if the update occurs in another thread.
- * There may be a performance penalty for such tight coupling between threads.
- * <p>
- * Unlike {@code MutableCallSite}, there is no
- * {@linkplain MutableCallSite#syncAll syncAll operation} on volatile
- * call sites, since every write to a volatile variable is implicitly
- * synchronized with reader threads.
- * <p>
- * In other respects, a {@code VolatileCallSite} is interchangeable
- * with {@code MutableCallSite}.
