Review Comment:
Intuitively, `cl.release()` may close the client (invalidating `cl`
instance), but it should never happen I believe (deferredClientRefs should have
a least one reference, and `CLIENTS_CACHE.computeIfAbsent` should add at least
one more), could we just do `cl.isClosed()` here?
```
if (deferredClientRefs.remove(cl)) {
cl.release();
if (cl.isClosed()) {
throw new IllegalStateException("The client has been closed
already");
}
}
```
WDYT?
