我们从Glassfish的3在服务器2008R2箱迁移到与Glassfish的4一切服务器2012R2盒去顺顺当当:-)直到我修改的一个应用程序，并尝试做新的箱子我第一次重新部署。为什么我无法重新部署Glassfish应用程序？
Glassfish的GUI引发此：
Error occurred during deployment: Keys cannot be duplicate. Old value of this key property, nullwill be retained. Please see server.log for more details. java.lang.LinkageError: loader (instance of org/glassfish/web/loader/WebappClassLoader): attempted duplicate class definition for name: "org/glassfish/web/loader/JdbcLeakPrevention" loader (instance of org/glassfish/web/loader/WebappClassLoader): attempted duplicate class definition for name: "org/glassfish/web/loader/JdbcLeakPrevention" java.lang.LinkageError: loader (instance of org/glassfish/web/loader/WebappClassLoader): attempted duplicate class definition for name: "org/glassfish/web/loader/JdbcLeakPrevention" loader (instance of org/glassfish/web/loader/WebappClassLoader): attempted duplicate class definition for name: "org/glassfish/web/loader/JdbcLeakPrevention"
而且server.log中包含：

我不知所措我为我所做的事情很多次类似的老没有问题的盒子。 Glassfish 4有什么不同，我会遇到这些问题？我还注意到，我无法“取消”应用程序（当我尝试时没有任何反应，就像它正在工作，但应用程序仍在那里）。我也尝试了“强制部署”选项来覆盖旧版本的应用程序，但它失败并显示相同的错误消息。
