After it unfreezes all works fine. It happens ever

Answer 1

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 !!!!!!

Answer 2

If anyone else is still having this problem, I found this related issue on the IntelliJ board: 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/hosts file:

127.0.0.1       localhost     <your hostname goes here>.local

And for IPv6 resolving, the same:

::1             localhost     <your hostname goes here>.local

Answer 3

The support from IntelliJ told me to try the IDE with bundled java.

http://download.jetbrains.com/idea/ideaIC-14.1.3-custom-jdk-bundled.dmg

And it works!

Edit:

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...

The solution for this is here.
