甲骨文形式经常挂

Question

无法理解为什么频频形式挂起，并试图分析线程转储。没有发现死锁。请帮我在这？

我测试在Oracle EBS形式的一些交易与我们的自动化工具（使用jemmy自动化）。在执行行动，形式变得反应迟钝。我使用的是最新的Java版本（1.8.0.201），IE11浏览器。

有时候，一旦窗体打开，一个动作之后的形式挂起。怀疑像僵局在那里。所以，把线程转储和它没有显示出deadlock.but许多线程等待状态，可运行状态。

例如我张贴在这个岗位两个线程踪迹。请建议如何发现问题，如果任何学习收获解释我。

这是一种内存不足的错误。

看来你需要应用补丁：21187539获得通过Oracle支持和使用Opatch实用程序12.1.0.2.0版及更高版本
