我使用的是Tomcat 6.0.29版本，JVM版本为1.6.0_51-b11-456-11M4508，来自Apple股份有限公司，运行在具有x86_64操作系统体系结构的Mac OS X 10.8.4版本上。这是因为我们使用的是老客户环境。
我正在使用IDEA和Ant一起构建web应用程序，构建脚本运行良好，除了第一次运行脚本之外，因为我后来遇到了构建错误。但是再次运行脚本可以使项目编译时没有任何问题。
但是web应用程序不会启动。当试图从Tomcat Web应用程序管理器启动它时，Tomcat说：FAIL-上下文路径/grgy上的应用程序无法启动，catalina.out写道：

This is very likely to create a memory leak.
2013-sep-04 20:00:54 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
ALLVARLIG: The web application [/grgy] created a ThreadLocal with key of type [null] (value [org.glassfish.gmbal.generic.OperationTracer$1@4749fee8]) and a value of type [java.util.ArrayList] (value [[]]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
2013-sep-04 20:00:54 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap

This is very likely to create a memory leak.

有什么想法吗？问题出在哪里？我应该如何让我的网络应用程序重新启动并运行？
谨致问候，乔纳斯
显然事情并没有那么复杂。。。
我再次阅读了catalina.out的日志，并注意到有一个线程正在等待JAMWikListener。在Tomcat Web应用程序管理器中，JAMViki的启动是正确的，但当我尝试使用该应用程序时，我收到了一条丑陋的错误消息，说该应用程序不工作（当然我在转述）。
因此，我从我的网络应用程序文件夹中删除了JAMViki应用程序，然后一切都恢复正常。
谨致问候，乔纳斯
