我的 NetBeans 8.2 在启动后冻结。我昨天安装了 8.2，使用大约一小时后关闭。几个小时后，我尝试再次使用它，它冻结了。我卸载了所有内容，安装了 8.1，使用它，在第二次启动时 8.1 开始显示相同的行为（它自发布以来一直正常工作）。我卸载了 8.1，再次安装了 8.2。它在第一次使用时可以正常工作，但之后它开始冻结。
只有在卸载/安装后才能正常工作。我已经尝试删除 C:\Users{my_user}\AppData\Roaming\NetBeans 8.x，但还是不起作用。我将 JDK 更新到最新版本（u112，我使用的是 u92），但同样的问题仍然存在。
以下是 messages.log 的内容：

有人知道会发生什么吗？
答案1
在这些情况下，准确诊断问题需要的是线程转储。它通常会给出冻结原因的线索。
NetBeans IDE 是基于 Java 构建的，而 Java 有 5 或 6 种不同的方法来获取正在运行的应用程序的线程转储（只需谷歌一下）。在这些方法中，首选的是所谓的Ctrl-Break 方法因为它是提供最多信息的方法。该方法的缺点是您需要从控制台窗口启动应用程序（在本例中为 NetBeans IDE）。但如果您可以始终如一地复制冻结，那么我认为这对您来说不是问题。如果您使用的是 Windows，请执行以下操作：
- 开始
cmd.exe - 从命令窗口启动您的应用程序，例如
C:\Program Files\NetBeans 8.2\bin\netbeans64.exe。 - 等待冻结发生。
- 现在按 Ctrl-Break在命令窗口中从步骤 1 开始。这将在命令窗口中打印一个线程转储。
- 将线程转储作为问题的一部分上传。（如果太大，则将其托管在某处）
Linux/MacOSX 的说明类似，尽管在步骤 4 中您需要QUIT使用 kill 命令向您的进程发送信号。
答案2
好吧，我真的不能说这是否 100% 确定，但在我看来，这似乎与我的显示器的使用方式有关。使用扩展桌面时，NetBeans 会冻结。仅显示主显示器或仅显示辅助显示器时，它可以正常工作。除非有人可以确认，否则我不会将此答案标记为正确。
