Description
When you configure a LoadBalancer for kie-server-client,
For example)
String LB_URL = "http://localhost:8180/kie-server/services/rest/server|http://localhost:8280/kie-server/services/rest/server"; KieServicesConfiguration config = KieServicesFactory.newRestConfiguration(LB_URL, USERNAME, PASSWORD);
RuleServicesClientImpl.executeCommandsWithResults() doesn't correctly fail over to server2 when server1 is down.
