我在我的maven项目中使用了JMockit 1.13。测试用例运行良好。但是现在我更新到了JMockit 1.17，现在我看到在控制台上运行这样的测试用例时出现了错误

当我将JMockit版本更改为1.13时，测试用例开始运行。我使用的是JUnit版本4.11。

如果您的单元测试运行时JRE使用的是java而不是java，那么对于仍在使用这个线程的任何人来说，造成这个问题的另一个原因是。

如果我将jdk1.8.0替换为jre1.8.0，就会得到上面的准确错误。

问题的答案就在Maven依赖树中:它表明类路径中存在多个版本的JMockit (org.jmockit:jmockit:jar:1.17、org.jmockit:jmockit-coverage:jar:1.11、com.googlecode.jmockit:jmockit:jar:1.7和com.googlecode.jmockit:jmockit-coverage:jar:0.999.26)。

删除比1.17更早的版本，如果同时使用覆盖率工具，请确保它与模拟库的版本相同。
