### What Operating System are you using (both controller, and any agents involved in the problem)?

Hi,

We're using the syslog library through this maven dep:

```

com.cloudbees
syslog-java-client
1.1.7


com.github.spotbugs
spotbugs-annotations



```

I'm trying to filter out error log writes such as this one:

`com.cloudbees.syslog.sender.TcpSyslogMessageSender - INFO: InetAddress of the Syslog Server have changed, create a new connection. Before=null, new=XXXXXXX
`

But no matter what I add to the log4j2.xml file, this error persists. Here's log4j2 appenders:
```


```

### Reproduction steps

1. add the dep
2. set log appenders to :
```


```
3. try to send a syslog message with a faulty IP
4. see the log still writes the error

### Expected Results

No log messages when adding:
```


```

### Actual Results

Error log writes appear

### Anything else?

_No response_

### Are you interested in contributing a fix?

Sure, can do.
