IntelliJ freezes for about 30 seconds before debugging
提问by Thomas
when i try to debug my java app the IDE freezes for about 30 seconds with the message: "Finished, saving caches"
当我尝试调试我的 Java 应用程序时，IDE 冻结了大约 30 秒并显示以下消息：“已完成，正在保存缓存”
After it unfreezes all works fine. It happens every time.
解冻后一切正常。它每次都会发生。
When i only run (not debug) it does not freeze.
当我只运行（而不是调试）时，它不会冻结。
What i tried:
我试过的：
- I changed the JDK on system.
- I changed the IntelliJ version.
- I change to IntelliJ Ultimate - trial.
- Invalidating the IDE's cache.
- Similar problem
- I also figured out that the given message exists only it this area of code - github-projectso i changed the JVM options to give InteliJ more ram.
- 我更改了系统上的 JDK。
- 我更改了 IntelliJ 版本。
- 我改用 IntelliJ Ultimate - 试用版。
- 使 IDE 的缓存无效。
- 类似问题
- 我还发现给定的消息只存在于这个代码区域 - github-project所以我改变了 JVM 选项来给 InteliJ 更多的内存。
InteliJ build IC-141.1010.3.
InteliJ 构建 IC-141.1010.3。
When i try to debug in other IDE's it works fine, only InteliJ gets stuck...
当我尝试在其他 IDE 中调试时，它工作正常，只有 InteliJ 卡住了...
I submitted a ticket to jetbrains too, but i know the power of StackOverflow :)
我也向 jetbrains 提交了一张票，但我知道 StackOverflow 的力量：)

If anyone else is still having this problem, I found this related issue on the IntelliJ board: https://youtrack.jetbrains.com/issue/IDEA-157303
如果其他人仍然有这个问题，我在 IntelliJ 板上发现了这个相关的问题：https: //youtrack.jetbrains.com/issue/IDEA-157303
It seems the problem is related to resolving hostnames. The recommended workaround is to include the following line in your /etc/hostsfile:
问题似乎与解析主机名有关。建议的解决方法是在您的/etc/hosts文件中包含以下行：
127.0.0.1 localhost <your hostname goes here>.local
And for IPv6 resolving, the same:
对于 IPv6 解析，相同：
::1 localhost <your hostname goes here>.local

Well, the issue took me around 3 hours to find out how to overcome it. For anyone has tried "modifying etc host file" solution from Jayson Minard and still not worked. Just go to SystemPreference -> Sharing and turn on File Sharing. That's on and it will let you debug your Java app on IntelijIdea 2017 very very very fast !!!!!!
好吧，这个问题花了我大约 3 个小时才找到解决方法。对于任何人都尝试过 Jayson Minard 的“修改等主机文件”解决方案，但仍然没有奏效。只需转到 SystemPreference -> 共享并打开文件共享。这样就可以了，它可以让您在 IntelijIdea 2017 上非常非常非常快地调试 Java 应用程序！！！！！！

The support from IntelliJ told me to try the IDE with bundled java.
IntelliJ 的支持告诉我尝试使用捆绑的 Java 的 IDE。
http://download.jetbrains.com/idea/ideaIC-14.1.3-custom-jdk-bundled.dmg
http://download.jetbrains.com/idea/ideaIC-14.1.3-custom-jdk-bundled.dmg
And it works!
它有效！

IntelliJ support feedback:
The problem was that there was a hang within java.net.Inet4AddressImpl.getLocalHostName(Native Method)JDK method call, which gets your system hostname. This is either JDK problem or local configuration issue...
IntelliJ 支持反馈：问题在于java.net.Inet4AddressImpl.getLocalHostName(Native Method)JDK 方法调用中出现挂起，它获取您的系统主机名。这是JDK问题还是本地配置问题...
The solution for this is here.
解决方案在这里。
