> [PR 2402|https://github.com/apache/solr/pull/2402] added support for
> CompletableFuture which accidentally introduced a double registration bug in
> HttpJettySolrClient by calling onRequestQueued/onComplete twice with
> asyncListener.queuedListener/completeListener
> This introduces three undesirable scenarios:
> # Potential deadlock due to a surge in requests that all acquire 1 permit
> and cannot acquire a second
> # Unnecessary system throttling when a request acquires a single permit but
> can't acquire a second due to in flight requests and new requests that
> arrived after the first token acquisition but before the second.
> # Half the number of permits available
