java - 在 javafx webview 中加载 URL 会导致 JVM 崩溃

Question

我正在将一些 url 加载到 javafx webview 中。我在这里使用 javafx webview 及其引擎进行爬行操作。然而，JVM 经常崩溃。我无法从下面的崩溃日志中看出任何内容。请帮忙。

WebView 存在一个已知问题，会迫使 JavaVM 崩溃，并在 https://javafx-jira.kenai.com/browse/RT-35262 处提交 EXCEPTION_ACCESS_VIOLATION。 (不幸的是，需要免费的 Jira 帐户)。

WebView 似乎在垃圾收集已发出的 JavaScript 语句方面存在问题，因此在使用一定量的 JavaScript 后，它将关闭 JVM。我们仅在 32 位 JVM 上观察到这一点。

修复已从 Java 8u40 推迟到 Java 9，甚至还没有计划(模糊地可能是在 2016 年)。
