Problem Description

Preconditions

A normal Spring Boot web project with module-info.java, using slf4j logback logging, see the last section for environment information

问题

When I shut down the Java process (kill ), occasionally the following error stack appears:

Exception in thread "SpringApplicationShutdownHook" java.lang.NoClassDefFoundError: ch/qos/logback/classic/spi/ThrowableProxy
        at ch.qos.logback.classic.spi.LoggingEvent.<init>(LoggingEvent.java:119)

Caused by: java.lang.ClassNotFoundException: ch.qos.logback.classic.spi.ThrowableProxy

It looks like the problem occurs in org.springframework.context.support.AbstractApplicationContext#doClose (AbstractApplicationContext.java:1070)

问题描述

前提条件

一个普通的Spring Boot Web 项目, 含有 module-info.java, 使用 slf4j logback 日志记录, 环境信息见最后一节

问题

当我关闭 Java 进程时 (kill ), 偶尔会出现如下错误堆栈:

Exception in thread "SpringApplicationShutdownHook" java.lang.NoClassDefFoundError: ch/qos/logback/classic/spi/ThrowableProxy
        at ch.qos.logback.classic.spi.LoggingEvent.<init>(LoggingEvent.java:119)
        at ch.qos.logback.classic.Logger.buildLoggingEventAndAppend(Logger.java:419)

Caused by: java.lang.ClassNotFoundException: ch.qos.logback.classic.spi.ThrowableProxy

看起来问题发生在 org.springframework.context.support.AbstractApplicationContext#doClose 方法 (AbstractApplicationContext.java:1070)

Comment From: bclozel

Is the JAR being updated or removed while the shutdown hook is being executed?
