I smells like an SecurityManager.
我闻起来像一个安全经理。
It is a message from the Java Security-Manager not from the filesystem. A class within this jar-archive tries to access a file, which is not allowed by the policy.
这是来自 Java 安全管理器的消息，而不是来自文件系统的消息。此 jar-archive 中的类尝试访问策略不允许的文件。
Take a look at this really similar problem: http://www.mkyong.com/tomcat/tomcat-javasecurityaccesscontrolexception-access-denied-loggingproperties-read/
