Unable to Set Notice Context

[micah-williamson]

Because the AirbrakeAppender initializes it's own Notifier, I am unable to add a NotifierFilter to inject additional notice context.

How can I add additional context/env/param to all notices when using log4javabrake?

Notifier notifier = new Notifier(conf.getAirbrakeProjectId(), conf.getAirbrakeProjectKey());
notifier.addFilter((Notice notice) -> {
    notice.setEnvironment("instance_id", conf.getInstanceId());
    return notice;
});
Airbrake.setNotifier(notifier);

Logger logger = LogManager.getLogger("com.acme.foo"); // <- uses different notifier
