JxBrowser -呈现通道已经关闭- ipc日志: OnRenderViewGoneMessage
JxBrowser -呈现通道已经关闭- ipc日志: OnRenderViewGoneMessage
提问于 2019-01-28 06:18:59
我有一个用Swing编写的Java应用程序，它使用JxBrowser (jxbrowser-6.18)。
我们正在加载一个本地url (http://localhost:8000/someLink.html)，然后在浏览器上运行一些定制的js。在某个时候，java代码中会抛出以下异常：
CERROR 2019-01-25 07:38:29,801 - Exception in thread "AWT-EventQueue-0"
CERROR 2019-01-25 07:38:29,801 - java.lang.IllegalStateException: Channel stream was closed before response has been received.

我检查了ipc日志，查找在07:38:29附近发生的事件

正如我们从日志中看到的那样，呈现通道在某个时候关闭。
OnRenderViewGone - terminationStatus=6，错误代码=-536870904
如果你有任何想法，我应该往哪个方向看，或者错误代码或终止状态意味着什么--请告诉我。我在网上搜索，但找不到任何有用的信息。
请注意，我没有复制这个问题，所以如果您对我如何复制它有任何想法，请告诉我。

1)如果尝试访问已被释放的浏览器实例，则会得到此异常。例如，如果使用Browser.dispose()方法释放浏览器实例，然后尝试调用其Browser.loadURL()方法，则会得到以下IllegalStateException错误消息。请确保在Java代码中不要使用已经释放的浏览器实例。如果在不同的线程中使用相同的浏览器实例，那么请确保在一个线程中不要释放它，而在另一个线程中使用已经释放的浏览器实例。
要检查浏览器实例是否已被释放，可以使用Browser.isDisposed()方法。
( 2)浏览器实例因Chromium中的一个问题而被意外处理。默认情况下，在Windows平台上，当Chromium崩溃时，JxBrowser生成jxbrowser-chromium.dmp崩溃转储文件，并将其存储在%localappdata%\JxBrowser\目录中(例如，c:\users\appdata\local\JxBrowser\jxbrowser-chromium.dmp). )。请检查这个位置，并与我分享所有的崩溃转储文件，您看到使用一个在线文件共享服务，如谷歌驱动器，Dropbox等。看看教程，描述如何获得崩溃转储文件在不同的平台。
3)如我所见，您正在使用JxBrowser 6.18版本。我建议您将库更新到6.22.2，因为最新版本包含了许多新特性、更新的铬引擎和大量稳定性修复，包括与呈现过程失去连接时的修复。
