Java 无法在tomcat6上启动grails war

当我尝试部署grails应用程序时，我在catalina.out中得到了这一点：

Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Feb 9, 2012 10:32:25 PM org.apache.catalina.core.StandardContext start

运行Grails2.0、Tomcat6和Ubuntu 10.04。我以前从未见过类似的情况，这是我正在做/可以修复的事情还是Tomcat的设置方式？

真正的错误将出现在日志目录中的另一个日志文件中。线程泄漏消息是一个问题，但这是关机时的一个问题。您的启动失败就是问题所在，在您所展示的内容中，除了

SEVERE:Context[/application]由于以前的错误而导致启动失败之外，根本没有对其进行描述
您是否碰巧运行了backgroundthread插件？我看到Tomcat没有响应，因为插件没有放弃线程并阻止服务器正确关闭
