Randomly offending lines of code:

client.apps().deployments().inAnyNamespace().list().getItems().stream()
    .filter(d -> !d.getMetadata().getNamespace().startsWith("xyz")
            && !d.getMetadata().getName().contains("operator"))
    .collect(Collectors.toList());

or

CustomResourceDefinitionList crdList = client.customResourceDefinitions().list();
CustomResourceDefinition voyagerIng = crdList.getItems().stream().filter(crd -> "ingresses.voyager.appscode.com".equals(crd.getMetadata().getName())).collect(Collectors.toList()).get(0);

or

ScalableResource<Deployment, DoneableDeployment> sr = client.apps().deployments().inNamespace(namespace).withName(name);
return sr.get();

@RisingPhorce : ah, we have some problems with connection leaks happening at some places across code e.g #1090 . Are you able to reproduce connection leak consistently? A test case for generating leak would be extremely helpful :) .
