jMockit 执行测试时出现 java.lang.ExceptionInInitializerError 异常的解决办法

jMockit执行时出现了错误java.lang.ExceptionInInitializerError ：

这个问题有可能是因为classpath配置不正确导致的，首先要看windows的环境变量中是否有classpath，如果没有要加上classpath，并确保classpath中有%JAVA_HOME%\lib\tools.jar;

如果在classpath中添加了tools.jar依然不能解决问题，需要看eclipse的jdk环境配置是否有问题，打开运行配置，选择JRE选项卡，确保这里使用的JRE是系统JAVA_HOME指向的JRE。
