JarvisCraft opened a new pull request, #12290:
URL: https://github.com/apache/lucene/pull/12290

   ### Description
   
   Current implementation of `ByteBufferGuard` uses an implementation-based 
assumption that `AtomicInteger#lazySet` causes full-barrrier (ie `[prior 
stores] happen before [following loads & stores]` is required).
   
   Since `VarHandle` appearance there have been explicit methods for performing 
memory fences including full fence thus it seems reasonable to rely on them 
rather than ungaranteed semantic.
   
   It's worth mentioning that unlike #9824 which proposes to use new explicit 
access modes on the field, this does not change the type of `invalidated` or 
its access methods but simply replaces the old non-obviously invoked barrier 
with an obvious one.
