Review comment:
My goal is to close connections that have the same clientId in different
nodes.The following code already done the logic which your mentioned .
```
private String validateClientId(String clientId, boolean cleanSession) {
if (clientId == null || clientId.isEmpty()) {
// [MQTT-3.1.3-7] [MQTT-3.1.3-6] If client does not specify a
client ID and clean session is set to 1 create it.
if (cleanSession) {
clientId = UUID.randomUUID().toString();
} else {
// [MQTT-3.1.3-8] Return ID rejected and disconnect if clean
session = false and client id is null
return null;
}
} else {
MQTTConnection connection =
session.getProtocolManager().addConnectedClient(clientId,
session.getConnection());
if (connection != null) {
// [MQTT-3.1.4-2] If the client ID represents a client already
connected to the server then the server MUST disconnect the existing client
connection.disconnect(false);
}
}
return clientId;
}
```
I think I am almost revised, I will update after the test is completed.
