Spring Security 3 ASM Jar包问题

在SPRING 官方网站上下载了Spring Security3.2的源码，运行里面的spring-security-samples-insecure这个Demo,使用Maven生成war包，放入到TOMCAT7下允许，JDK版本使用是1.6.0.45,启动时总是报如下异常：

在网上查了原因，说是Spring-asm.jar 在Spring3.2以后就被集成到Spring-core.jar包里面，所以不需要单独引入Spring-asm.jar的jar包。而我的工程里面根本没有引入。
想来想去找不到解决方案，网上说有可能是JDK版本的问题，我试着换成MyEclipse8.6自带JDK，版本是1.6.0.13，居然成功了，我又换成JDK1.7，也是OK，应该是我JDK版本的问题，我修改了我的JDK文件。
特此记录一下。以防备用。[url]http://docs.spring.io/spring-security/site/docs/3.2.x/guides/helloworld.html[/url]官方的步骤

工程已经上传，可以直接放入到tomcat下运行。
