尝试在 OpenJDK 6 上使用 JMockit 运行测试时，我遇到了以下错误：

我查看了文件夹 /usr/local/openjdk6/jre/lib/amd64/ 并在那里找到了libattach.so

但是添加-Djava.library.path=/usr/local/openjdk6/jre/lib/amd64并没有解决问题。我还能尝试什么？

尝试在jmockit.jar之前<jdk6home>/lib/tools.jar添加到类路径。如果这不能解决问题，那么绝对应该作为 JVM 初始化参数传递。-javaagent:jmockit.jar

在我的案例中，我注意到我指向的是 JRE6 而不是 JDK6。一旦我将我的 JAVA_HOME 指向 jdk6，它就解决了问题
