在富 UI 应用程序中使用 WebView 时出现 JavaFX StackOverflowError

Question

我在使用 WebView 时遇到问题，当我加载它时，它看起来全是彩色闪烁，然后直接进入 stackOverFlowError。

对我来说似乎是一种递归。我不认为通过 -Xss 增加堆栈大小（已经尝试过）在这里会有所帮助。 我有哪些选择？

这可能是由 BIG SCENE GRAPH 引起的吗？我有相当重的图形密集型 UI 553 节点当主视图打开时，266 节点当浏览器页面加载时。在分离的 FXML 文件和分离的控制器中。

GMaps 出错（使用 webView）：

可以在我之前的问题中找到正在发生的事情的图片：https://stackoverflow.com/questions/25247703/javafx-webview-rendering-graphical-glitches 当时我还没有收到这个错误，只是一个小故障。现在它把我带到了这个。

在某些更改后，仅图形故障不会引发异常芽（转到页面 google.com -> sector.sk -> facebook.com 等 stackoverflow 被抛出。我最多可以更改 1/2 个网站，然后它抛出的应用程序停止回应。）

-Xss 现在是默认值。 据我所知，我使用的是最新的javafx and java 8 u20。

Answer 1

您可以使用 SystemProperty glass.lens.stackSize 来设置堆栈 JavaFX ApplicationThread 的大小。 它是作为https://javafx-jira.kenai.com/browse/RT-36811 的一部分实现的。

一旦我们切换到单片眼镜，这可能会更改为 glass.monocle.stackSize 尽管。

您也可以在生成的 android 项目中设置属性 - 在 Jvm 参数下的 AndroidManifest.xml 中（添加 |-Dglass.lens.stackSize=128000) 或者 - 在 assets/javafx.platform.properties 中（添加行 android.glass.lens.stackSize=128000)

还没有尝试过，但这应该会将stackSize增加到128KB， 即使对于非常复杂的应用程序，这也应该绰绰有余。

如果它对您有用，请告诉我们。
