java.lang.ClassFormatError : Absent Code attribute in method that is not native or abstract in class file javax/mail/internet/ParseException

Question

我以前见过这个问题，但我的情况似乎有所不同。当我在一个独立的 java 程序上运行 junit，该程序通过 pop3 从 smtp 服务器检索电子邮件时，就会发生这种情况。

我见过很多问题，他们都说这是因为它试图运行一个没有 javaee 实现的接口(interface)。但我没有使用 javaee、jboss、glassfish 等。该程序仅使用 JDK 1.7 作为后台守护进程运行，没有应用程序服务器。

编辑

我添加了一个屏幕截图，其中包含 Maven 加载的依赖项。我没有看到任何javaee: Dependencies

Answer 1

检查您的依赖项之一是否未拖入某些其他版本的 JavaMail 或某些 javaee.jar 文件。

另请注意，您使用的是非常旧版本的 JavaMail。当前版本为1.5.6，获取here .
