I am using the Fabric8 Java library to access the Kubernetes API within an actor system. I am concerned about connection leaks and want to understand how the client connections are closed underneath after a REST call is made

Here is the code that initializes the client:

config = new ConfigBuilder()
  .withMasterUrl(apiServer)
  .withOauthToken(token)
  .withTrustCerts(true)
  .build();
client = new DefaultKubernetesClient(config);

This client is then passed on to various actors, how should I be closing these connections in the actors so that connections don't leak or are abandoned hen a certain actor dies?
