Answer 1

Was the same problem, tried everything and only completely deleted Java 7 and installed Java 6 JDK solved problem!

Answer 2

No need to disable IPV6. Just force Eclipse to use IPV4. Edit eclipse.ini and add the last line:

openFile
-vmargs
-Djava.net.preferIPv4Stack=true

Answer 3

Had the same problem here. My problem was a firewall issue. I use VirtualBox sometimes and found that the virtual machine's network adapter was the roadblock. Disabling the virtual adapter in Windows device manager solved my issue.

Answer 4

Solution : turn off Teredo Tunneling Pseudo-Interface.

This probably converts IP4 to IPv6 addresses or something, resulting in an IPv6 address for your localhost (strange though, that a PING still results in IP4). Anyway, turning it off (Device manager > View > Show hidden devices > right click on Teredo > disable) solves the problem!

I found out by doing a ipconfig /all in the NON working situation. It showed :

//edit : I guess it's technically a workaround untill Eclipse supports IPv6

I had the same problem with my Killer Networks Wireless card N-1103. I found that installing the latest driver from their website cured it

Answer 6

Ahah!! Finally fixed this one. It was a problem I believe with my bigfoot killer network

So, here is what I did.

Open CMD as administrator ( Right click, open as administrator ) Type: "netsh winsock reset"

Restart the computer

When it comes up saying: "Your LSP is not mapped correctly, would you like to re map it?" Click "NO"

Then all is well..

Only now, I do have it asking me about LSP mapping each time I boot, this f
