Oh, so it is. OK.

No, I made the mistake of reading the description, which doesn't seem to help:

     * Version of {@link #putObjectVolatile(Object, long, Object)}
     * that does not guarantee immediate visibility of the store to
     * other threads. This method is generally only useful if the
     * underlying field is a Java volatile (or if an array cell, one
     * that is otherwise only accessed using volatile accesses).

I didn't spot this:

     * Corresponds to C11 atomic_store_explicit(..., memory_order_release).
