大家下午好/晚上好；
我今天写的这篇文章是关于我最近在使用 Java 时遇到的一个奇怪问题:每当我尝试运行 Java 应用程序时，它就会崩溃!我搜索了无数网站，多次卸载并重新安装 Java，甚至询问了一些程序员同事。似乎没有人知道这里发生了什么。
到目前为止，我只有两个潜在的线索:首先，我是 ZoomText 用户(ZoomText 是一个屏幕放大程序)，当 ZoomText 关闭时，Java 可以正常工作(据我所知)；所以这可能是 Java 和 ZoomText 之间的一些内部/系统级“分歧”。其次，每次崩溃时(所以每次启动 Java 时)我都会得到这些奇怪的文本文件，标记为 hs_err_pid ，后跟随机数。以下是其中一个文件的示例:

现在我已经编写 Java 足够长的时间了，知道这绝对不是 Java 代码 - 它几乎看起来像是加密的东西，或者是位或字节级的东西，一些我喜欢的深暗操作系统级的东西理解但还没有。也许只是我的电脑告诉我停止编写 Java 并切换到 Python 或 PHP! :)
说真的，我以前从未见过这样的事情，而且我完全不知道还能做些什么来解决它。它不仅仅影响我创建的应用程序——它影响任何甚至使用 Java 的事物。我点击任何运行 Java 的东西都会崩溃。
但无论如何，这是我在 Google 上找到的更多信息。显然，玩“我的世界”游戏的人也遇到了同样的问题，尽管似乎没有人找到解决方案。一个人说这是一个驱动程序的问题，你需要卸载/重新安装驱动程序(这对我来说听起来像是一个冒险的计划；但话又说回来也许不是；我还不知道驱动程序的东西，所以也许是这样)。还有一个人说这与清除 Java 缓存有关(我尝试过)，另一个人认为这与“显卡”有关(遗憾的是我对硬件的了解少于对驱动程序的了解)。但我认为其中一些理论可能会有所帮助。
预先感谢您提供有关该主题的任何见解或信息。我真的很感激。
最佳答案
这里有一些有用的线索:
- 只有当您使用 ZoomText 时才会发生这种情况
- 崩溃线程的堆栈帧转储在几个地方提到了 AccessBridge。
由此看来，问题与 Java 的辅助功能支持有关。更准确地说，它看起来像是在 Java 和 native 代码之间的回调交互期间发生的，其中涉及对名为的方法的调用:
com.sun.java.accessibility.AccessBridge.getAccessibleNameFromContext
我扫描了 Oracle Java Bug 数据库，没有发现任何相关内容。
