Changes:

Renamed DAO field variables to follow proper camelCase naming conventions (_lb2stickinesspoliciesDao → _lb2StickinessPoliciesDao, _lb2healthcheckDao → _lb2HealthCheckDao)
Modernized code by using diamond operators for generic type inference and simplifying conditional logic
Fixed spelling errors in code comments ("comparisions" → "comparison", "assoication" → "association")
Improved variable naming for better readability (e.g., priIp → primaryIp, lstVmId → vmIds, maps → lb2VmMaps)

                            logger.debug("Load balancer rule {} is removed for Instance {} and IP {}",

+                                    lb, lbVmMapToRevoke.getInstanceId(), lbVmMapToRevoke.getInstanceIp());;


Double semicolon at the end of the statement. Remove one semicolon.

Suggested change

lb, lbVmMapToRevoke.getInstanceId(), lbVmMapToRevoke.getInstanceIp());;

lb, lbVmMapToRevoke.getInstanceId(), lbVmMapToRevoke.getInstanceIp());

        }
-        lstVmId.add(new Long(vmId));
+        vmIds.add(new Long(vmId));


The explicit Long constructor call is unnecessary and deprecated. Use Long.valueOf(vmId) or simply add vmId directly since autoboxing will handle the conversion.

Suggested change

vmIds.add(new Long(vmId));

vmIds.add(vmId);

Missing space after comma in method call arguments. Add space after the comma for better readability.

Suggested change

Redundant call to 'toString' on a String object.

Suggested change

logger.debug("Set load balancer rule for revoke: rule {}, vmId {}, vmIp {}", loadBalancer::toString, () -> _vmDao.findById(instanceId), vmIp::toString);

logger.debug("Set load balancer rule for revoke: rule {}, vmId {}, vmIp {}", loadBalancer::toString, () -> _vmDao.findById(instanceId), vmIp);
