无法理解为什么表单频繁挂起并尝试分析线程转储。发现没有死锁。请帮我解决这个问题？
我正在使用我们的自动化工具(使用 jemmy 进行自动化)在 Oracle EBS 表单上测试一些事务。在执行操作时，形式会变得没有反应。我使用的是最新的java版本(1.8.0.201)，IE11浏览器。
有时，表单一打开，并且在执行一个操作后，表单就会挂起。 怀疑那里有僵局。因此进行了线程转储，它没有显示死锁。但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堆栈跟踪。 请建议如何找到问题并解释我是否有任何学习。

最佳答案
It's a kind of Out Of Memory errors.
您似乎需要通过 Oracle 支持应用补丁:21187539，并使用 Opatch Utility 版本 12.1.0.2.0> 以及稍后
