Java NetBeans 8.2 IDE、JDK 1.8中的光标不稳定。键盘滞后？

我有一个学生，在MacBookPro（High Sierra）上的NetBeans 8.2和JDK 1.8.x下，他的光标不规则地跳跃。其他应用程序工作正常，但当他开始在NetBeans中键入时，他会得到一个延迟，然后光标会向左或向右跳转几个字符，可能会出现他键入的其中一个字符，但不是所有字符。如果他在两次按键之间停顿，比如说，0.5秒，效果很好，但这当然是站不住脚的。 我重新安装了一个新的安装，并有相同的问题。有人能帮忙吗？这是我无法理解的。短暂性脑缺血发作 谢谢你，斯科米萨。这是一些日志文件。没有错误

当这个学生在家工作，他的祖父在电脑上工作时，这个问题就消失了。他的解决方案如下。我是在学校环境中这样做的，现在似乎在一个句子中键入字符可以正常工作，但当我按CR或backspace或删除一行或多行时，会出现很大的延迟（2-3秒？）

步骤1：进入系统首选项>网络>选择wifi连接>高级>选择代理选项卡。 然后检查3个选项1）自动代理发现2）自动代理配置3）web代理（http）

步骤2：转到netbeans>首选项>常规>选择使用系统代理>重新加载>测试连接

步骤3：如果连接成功，则在netbeans中清理并构建应用程序，然后按run

出现此问题的原因可能是，默认情况下，High Sierra更新可能会阻止使用系统代理设置的站点。当Avery将最新的操作系统安全更新更新更新到10.13.4（昨天刚刚发布）时，他可能会再次遇到相同的问题。

在另一位用户中，他还报告“插入单个字符可能需要半秒钟”，但该问题是在Linux上出现的，尚未解决。需要检查的三件事[1]确保您使用最新的JDK更新（8u162）运行。[2] 如果您使用的是特殊外观（如Darcula），请尝试还原为默认外观。[3] 如果您使用的是任何特殊字体，请尝试还原为默认字体。此外，键入速度慢的问题是仅适用于*.java文件，还是适用于所有文件类型？例如，创建一个简单的文本文件并在NetBeans中编辑它。打字还是很慢吗？如果是这样，请使用NetBeans日志更新您的帖子：从“视图”菜单中选择“IDE日志”以显示该日志。问题似乎也存在于其他文件中（至少在文本文件中）。我将把日志文件添加到我的原始问题中。哦，这里的noobie不知道如何附加文件。Netbeans日志文件太长，无法粘贴到我的原始帖子中。只需检查以警告或错误为前缀的邮件，如果这些邮件似乎相关，请使用这些邮件更新您的帖子。可能没有。另外，从那个日志中，你们可以用五行前缀来更新你们的帖子：产品版本、操作系统、Java；虚拟机；供应商、运行时和Java主页。它们将在日志的开始处。因此，您是否可以尝试在同一台计算机上使用有线连接来查看哪些问题（如果有）得到解决？如果不使用无线连接时一切正常，那么至少您知道问题所在！另外，Mac Os 10.13.4上的另一位Mac用户有光标/滚动条问题，这些问题通过使用更新版本的NetBeans进行修复。在您的情况下，这可能不是一个选项，但请看一下：
