Review comment:
While this might not be 100% proof I prefer the following:
```java
private final AtomicReference<Supplier<? extends Collection<HostEntryPair>>>
keysSupplierHolder = new AtomicReference<>(getKnownHostSupplier(null,
getPath()));
```
And then replace the relevant sections with:
```java
keysSupplierHolder.set(....);
```
