Connection to influx still active even after calling influxdb.close();

Connection to influx still active even after calling `influxdb.close();`

Here is my **Test Code**

```
public static void main (String[]args){
InfluxDB influxDBConnection;

for (int i = 0; i < 10; i++) {
try {
QueryResult queryResult;
influxDBConnection = InfluxDBFactory.connect("url", "username", "password");
queryResult = influxDBConnection.query(new Query("select value1 from test_measurement1", "test_db"));
System.out.println(queryResult.getResults().get(0).getSeries().get(0).getValues().get(0).get(1).toString());
influxDBConnection.close();
Thread.sleep(10000);
} catch (Exception e) {
e.printStackTrace();
}
}
}
```

After execution of following code 10 connections are made even after calling the close method.
I checked the number of connection made to influxdb through `netstat`.

Is there any way to close the existing influx connection?

Start by reproducing the provided loop and checking the connection behavior with netstat. Read the InfluxDBFactory.connect and InfluxDB.close lifecycle documented or exposed by the client; done means repeated connect/close calls do not leave the observed connections active.
