为什么Tomcat在取消部署期间抛出'java.lang.IllegalStateException：Class invariant violation'？

我有一个web应用程序（Tomcat 6，log4j 1.2.16），它以一个监听器开始。取消部署应用程序将引发以下异常：为什么Tomcat在取消部署期间抛出'java.lang.IllegalStateException：Class invariant violation'？

HqListener.java是我的监听器和它报告一个成功关机。

如何摆脱此异常消息？

您可能搜索在log4j中的配置，我有类似的问题与tomcat6中的应用程序，在tomcat5.5中工作“很好” –

检查您的解决方案这个JIRA错误：http://java.net/jira/browse/GLASSFISH-16767

类似的解决问题的计算器在这里：Undeploying a Grails App from Glassfish gets a Class invariant violation

在Glassfish的domain.xml文件设置该属性

<jvm-options> 
    -Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES=false 
</jvm-options>

解决问题;不知道在Tomcat中设置此位置，可能server.xml？

您可以提供示例domain.xml放置此属性的位置。它是系统属性吗？ – kinkajou

将此添加到domain.xml的的jvm选项中，这通常是找到的在install-dir/glassfish/domains/domain1/config中： -Dorg.apache.catalina.loader.WebappClassLoader.ENABLE_CLEAR_REFERENCES = false – Oversteer

我解决这个问题的方式（在glassfish环境中）是避免将记录器声明为静态的，例如，

private static final Logger logger = LoggerFactory.getLogger(BootStrapListener.class);

如果从上述声明中删除static，将不会再出现上述错误。
