Servlet2.5版本ear不在WebSphere8.5中启动

Question

我在Servlet2.5版本中部署了一个内部带有唯一war的ear。当我尝试启动应用程序时，日志显示此消息，服务器尝试无限地启动应用程序。它在抛出java HeapException 20分钟后结束。

如果我部署相同的ear，但使用Servlet2.4版本，当我启动应用程序时，它会在几秒钟内启动。

WAS 8.5和servlets 2.5规范的问题是什么？

Answer 1

在不了解应用程序内容的情况下，我只能假设正在进行广泛的类路径扫描（Java EE6/Servlet2.5中引入了大量注释）。您应该在应用程序部署期间检查减少注释搜索，以获得可能的解决方案。
