Question

无法理解为什么表单经常挂起并尝试分析线程转储。没有发现僵局。请帮我吗？

我正在使用我们的自动化工具（使用jemmy进行自动化）在Oracle EBS表单上测试某些事务。在执行动作时，表单变得无响应。我正在使用最新的Java版本（1.8.0.201），IE11浏览器。

有时，表单打开后，执行一项操作后，表单将挂起。疑似死锁在那里。因此进行了线程转储，没有出现死锁。但是许多线程处于等待状态和可运行状态。

例如，我在这篇文章中发布了两个线程的堆栈跟踪。请提出问题的查找方法，并向我解释。

这是一种内存不足错误。

似乎您需要应用补丁： 21187539 ，以获取Oracle支持并针对版本 12.1.0.2.0 使用 Opatch Utility >和以后
