几年前，我在我的 32 位系统上创建了一个 Java 聊天应用程序，并使用本机代码在收到消息并最小化窗口时实现窗口闪烁。我重新编译了使用 64 位编译器进行闪烁的 C++ 代码，并且我拥有 64 位 JRE 版本。但是，当尝试运行闪存时，出现异常。

下面是 C++ 代码，下面是日志文件的输出。感谢您的任何见解。

这个“异常”意味着你在 C 中访问了一个 NULL 值。

你能检查所有类型在 64 位中都没有变化吗？

也许这适用于 32 位，但无法找到 64 位版本。

hJAWT = LoadLibraryW(path2);

Netbeans 有一个调试器，它允许您通过 JNI 在 Java 和 C 中设置断点。这可以帮助您找到确切的线路以及它发生的原因。

有趣的是，我现在实际上正在开发一个非常相似的应用程序并且遇到了一个非常相似的问题。我在 64 位 Windows 7 上运行基于 JAWT 的应用程序，一旦我尝试使用任何代码JAWT awt;，它就会爆炸。如果您不介意，请为我尝试几件事，我们可以验证您是否遇到同样的问题（以及它是 Java 问题还是 Windows 问题，而不是我们的问题）：

  • 如果您在本机代码中删除所有对 JAWT 的引用，会发生什么情况。仍然调用您的本机函数，但只需删除对 JAWT 的所有引用。这应该会导致jawt.lib无法链接。根据我的经验，一旦我删除了对 JAWT 的所有引用，我的应用程序就会停止崩溃。
  • 如果您在本机代码中删除所有对您自己的东西的引用并且只做基本的 JAWT 初始化以获取JAWT_Win32DrawingSurfaceInfo. 它仍然崩溃吗？根据我的经验，即使本机代码除了初始化 JAWT 什么都不做，我的代码也会崩溃。
  • 如果您使用 JRE6 而不是 JRE7 运行会发生什么？对于我来说，我的应用程序在 Java 7 中立即崩溃，但在 Java 6 中运行良好。

有兴趣听听您是否看到相同的问题。我开始怀疑适用于 Windows 7 的 Java 7 是否引入了某种回归。还在做更多的测试。我会发布更多结果，因为我有它们。

==========================================

更新： 新的有趣皱纹。事实证明，对我来说，只需使用 System.load(...) 加载链接到jawt.lib 的DLL 就足够了。我什至不必实际拨打本地电话。在渲染我的 Swing GUI 时它仍然会崩溃。
