当我尝试在AIX 机器上运行我的项目时，我得到一个java.lang.IncompatibleClassChangeError。

  • 该项目使用JAXB API (2.0)生成 XML 文件。
  • 开发环境安装在Windows XP中，使用JDK1.5.0（与AIX机器的JDK相同）。
  • 在开发环境中，该项目运行良好。但在 AIX 机器中它不起作用（抛出异常）。

这是我尝试运行项目时的堆栈跟踪：

检查 AIX 上的类路径并确保您使用的是兼容版本的 jaxb-api 和 jaxb-impl 库。当只有次要版本相差一个增量时（例如 2.2.5 与 2.2.6），我遇到了 IncompatibleClassChangeError。

要检查您使用的每个库的版本以及兼容性所需的内容，请查看位于每个 jar 文件中 META-INF 目录中的清单文件。jaxb-impl 清单声明（除了它自己的版本）规范版本，这是它需要的 jaxb-api jar 版本。从 v2.2.2 开始，jaxb-api 和 jaxb-impl 兼容实例的版本号不再匹配：例如 jaxb-impl v2.2.4 与 jaxb-api v2.2.3 兼容

我只有使用 JAXB 的 Sun 实现 (com.sun.xml.bind) 的经验，因此如果您使用不同的实现，这可能不适用。
