NetBeans 8.2 IDE，JDK 1.8中的游标不正确.键盘滞后? [英] Erratic cursor in NetBeans 8.2 IDE, JDK 1.8. Keyboard lag?

问题描述

我有一个学生，他的光标在MacBook Pro(High Sierra)上的NetBeans 8.2和JDK 1.8.x下不正常地跳来跳去.其他应用程序可以正常工作，但是当他开始在NetBeans中键入内容时，会出现延迟，然后光标将向左或向右跳几个字符，也许会出现他键入的一个字符，但不是全部.如果他在两次按键之间停顿了0.5秒，那可以正常工作，但那当然是站不住脚的. 我重新安装了全新安装，并遇到了同样的问题.有人可以帮忙吗?这超出了我. TIA 谢谢skomisa.这是一些日志文件.没有错误.

解决方案

当学生在家工作并且他的祖父在计算机上工作时，问题消失了.他的解决方案如下.我是在学校环境中做到这一点的，现在似乎可以在单个句子中键入字符正常工作，但是当我按CR或退格键或如果删除一行或多行时，会有很大的滞后时间(2-3秒?). /p>

步骤1:转到系统偏好设置>网络>选择您的wifi连接>高级>选择代理标签. 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> preferences> general>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，则清除&在netbeans中构建应用程序，然后按run

之所以可能出现此问题，是因为默认情况下，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为10.13.4(昨天才可用)时，他可能会再次遇到相同的问题.

I have a student who experiences his cursor jumping around erratically under NetBeans 8.2 and JDK 1.8.x on a MacBook Pro (High Sierra). Other applications work fine, but when he starts typing in NetBeans, he'll get a delay, then the cursor will jump a couple characters, left or right, maybe one of the characters he types will appear, but not all of them. If he pauses for, say, .5 a sec between keypresses, it works fine but that, of course, is untenable. I reinstalled a fresh install and have the same problem. Can anyone help? This is beyond me. TIA Thank you skomisa. Here's some of the log file. No ERRORS.

解决方案

The problem disappeared when the student worked at home and his grandfather worked on the computer. His solution is below. I did that in the school environment and now it seems like typing characters in a single sentence works normally but when I press CR or backspace or if I delete one or more lines, there is a big lag (2-3 seconds?).

step 1: go to system preference >network>select your wifi connection>advanced>select proxies tab. Then check the 3 options 1) auto proxy discovery 2)automatic proxy configuration 3) web proxy(http)

step 2: go to netbeans>preferences>general> select use system proxy> reload> test connection

step 3: if connection is successful, then clean & build your applications in netbeans and press run

The problem probably happened because a High Sierra update by default might have blocked the sites which use system proxy settings. When Avery updates the latest OS security update to 10.13.4 (which just became available yesterday) he may encounter the same issue again.
