问题描述

我在MyFaces 2.0.0上确实遇到了令人讨厌的问题(更准确地说，我也在2.0.1和2.0.2上进行了检查，问题仍然存在).

I have got really annoying problem with MyFaces 2.0.0 (To be more precisely I checked it out also on 2.0.1 and 2.0.2 and problem remains).

我现在正在MyFaces下编写应用程序.简而言之，在我的应用程序中，我使用以下框架:Spring，Hibernate，JSF(MyFaces实现)我的应用程序容器是Tomcat(6.0.29版)我使用maven进行构建和部署(3.0版).

I'm writing now application under MyFaces. Briefly speaking in my application i use frameworks: Spring, Hibernate, JSF (MyFaces implementation)My application container is Tomcat (6.0.29 version)I use maven to build and deploy (version 3.0).

问题是，当我尝试通过maven(mvn tomcat:redeploy)重新部署应用程序时，它首先尝试取消部署应用程序，然后再次部署它.但是部署从未成功.我有信息:

The problem is when I try to redeploy application via maven (mvn tomcat:redeploy) it tries first to undeploy application and the deploy it again. But undeploying never suceed. I've got information:

SEVERE: The web application [/adam] created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.ThreadLocal@4b0a4d7c]) and a value of type
[org.apache.myfaces.config.RuntimeConfig] (value  org.apache.myfaces.config.RuntimeConfig@11652e61])
but failed to remove it when the web application was stopped.
This is very likely to create a memory leak.

由于此错误，tomcat无法取消部署应用程序:

Due to this error tomcat cannot undeploy application:

INFO: Undeploying context [/adam]
2010-12-02 11:47:46 org.apache.catalina.startup.ExpandWar deleteDir
SEVERE: [D:\Program Files\apache-tomcat-6.0.29\webapps\adam\WEB-INF\lib] could not be completely deleted. The presence of the remaining files may cause problems

2010-12-02 11:47:49 org.apache.catalina.startup.HostConfig deployDirectory

我在WEB-INF \ lib中的所有库以及保存Log4J日志的文件都无法删除.

All of my libraries in WEB-INF\lib and my file where i keep logs from Log4J cannot be deleted.

从提供ELFactoryImpl的库中也有连接的内存泄漏:

There is also connected memory leak from library that provides ELFactoryImpl:

SEVERE: The web application [/adam] created a ThreadLocal with key of type [null]
(value [org.apache.myfaces.el.convert.VariableResolverToELResolver$1@693985fc])
and a value of type [java.util.HashSet] (value [[]]) but failed to remove it
when the web application was stopped.
This is very likely to create a memory leak.

如何摆脱这种内存泄漏?

How to get rid of this memory leaks ?

很久以来我一直在寻找答案，但找不到任何解决方案.我在myface的jira上发现了此问题: https://issues.apache.org/jira/browse /MYFACES-2942 但是我不知道该怎么想.我应该等待版本2.0.3吗?

I have been looking for answer really long I cannot find any solution.I found this issue on myface's jira: https://issues.apache.org/jira/browse/MYFACES-2942But I don't know what to think about it. Should I wait for version 2.0.3 ?

我认为EL的内存泄漏与第一个有关.

I think that memory leak from EL is connected to first one.

请帮帮我！ ;)如果需要，我可以提供更多详细信息.

Please, help me ! ;) I can provide more details if needed.
