Raven 连接 java.lang.IllegalStateException：正在关闭答案

【问题标题】：Raven connection java.lang.IllegalStateException: Shutdown in progressRaven 连接 java.lang.IllegalStateException：正在关闭

【问题描述】：

我有一个非常基本的程序，可以连接到 PostgreSQL 数据库并测试 Sentry 日志记录是否有效。

但我不能优雅地关闭它。我做错了什么？

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.");
    }
}

我得到了这个例外：

顺便说一句，将 raven.async.gracefulshutdown 设置为 false 没有帮助。
