Raven connection java.lang.IllegalStateException: Shutdown in progress

Question

I have very basic program that connects to PostgreSQL database and tests if Sentry logging works.

But I can't shut it down gracefully. What am I doing wrong ?

package com.sample;

import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.LogManager;

public class Main {
    private static final Logger logger = LogManager.getLogger(Main.class);

    public static void main(String[] args) {

        logger.error("Random error");
        logger.trace("Exiting application.");
    }
}

I get this exception:

BTW, setting raven.async.gracefulshutdown to false doesn't help.

The problem was with raven-java itself, I've created pull request and It now fixed.
