以上报错是jdk1.4的jmx.jar本身bug，在1.4之后的版本修复，所以需要下载修复版本
官方解释：
The JMX technology provides the tools for building distributed, Web-based, modular and dynamic solutions for managing and monitoring devices, applications, and service-driven networks. By design, this standard is suitable for adapting legacy systems, implementing new management and monitoring solutions, and plugging into those of the future.
Starting with the J2SE platform 5.0, JMX technology is included in the Java SE platform. Please see the JMX documentation for the J2SE 5.0 and Java SE 6 platforms. Previous versions of JMX technology are available here.
