我使用 glassfish 3.1.2.2 服务器和 idea Ultimate Edition 11（在 Ubuntu 12.04 上）。当我部署我的耳朵项目时，有一个例外，首先是空指针，然后是 nosuchmethod。 在 glassfish 3.0.1 上它可以工作，但在 3.1.2 上不行。
服务器日志：

此类错误通常是由于类路径中存在同一库的两个不同版本所致。
请检查新版本的 glassfish 是否未附带您的应用程序正在使用和部署的库之一的标准版本。作为第一个到达犯罪现场的人:)，应用程序服务器将加载第一个类（标准类），这与您的应用程序想要使用的类不同。
强制使用不同的类加载器可以解决此类问题。不过，我没有使用 Glassfish 的经验，但在 Weblogic 上遇到过类似的问题。
对于我来说，当我将应用程序服务器从 glassfish 6.x 更改为 glassfish 7.0.2 时，我遇到了此错误，并且服务器无法启动。日志有错误说该方法不存在
com.sun.appserv.server.util.Version.getFullVersion()在我的项目属性中，我将 EE 版本从 9.1 更改为 EE10，然后我能够再次返回编码。
