Review Comment:
This creates infinite recursion. The method calls itself instead of
LOG.debug(). This should be 'LOG.debug(message, args);'.
```suggestion
LOG.debug(message, args);
```

Review Comment:
Creating raw threads is generally discouraged. Consider using a thread pool
or executor service for better resource management and control.
```suggestion
connectionWarmupExecutor.submit(() -> cacheExtraConnection(route,
cacheRefreshConnections));
```
