SpringBoot AsynchronousCloseException is thrown when shutdown Tomcat

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        try (var ctx = SpringApplication.run(DemoApplication.class, args)) {

        }
    }
}

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.4.0-M3'
    id 'io.spring.dependency-management' version 'latest.release'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'

repositories {
    mavenCentral()
    maven {
        url "https://oss.sonatype.org/content/repositories/snapshots"
    }
    maven {
        url "https://repo.spring.io/milestone"
    }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-web'
}

tasks.named('test') {
    useJUnitPlatform()
}

When I switch Spring Boot from 3.3.4 to 3.4.0-M3, it doesn't shutdown gracefully, no matter what server.shutdown is set.

Sorry, it seems caused by system proxy, close it.
