Eclipse Luna freezes in Java Debug

Question

Have you done some research on this issue, but could not find an answer to my circumstances.

Problem: I cannot start debugging for any Java applications in Eclipse Luna. In the progress window, I am informed that "Launch Main" and the progress bar continues to 85% where it hangs. At this point, I get the following under the progress bar, "Launch: search for a free socket ..."

Here is my setup:

• Eclipse Luna (clean install)
• Java - latest (1.7.0_65)
• Windows 7
• pinging localhost and 127.0.0.1 returns good connections
• Debugging worked fine with the old Juno installation.
• The project works fine, behaves correctly and returns data, but cannot be debugged.
• Avast does not work
• I start Norton (without first interfering with debugging)

Any ideas would be appreciated. I can’t understand what this error is. I am sure that the new variable added by Eclipse, which I have never heard of, should be set, but this is certainly disappointing.

Thanks guys.

Network layer timeouts usually indicate packet loss. This can be caused by incorrect network equipment or a firewall that is denied access.

If there is no network equipment, because it is located on your local machine, this is usually a problem with a software firewall. This can be verified by temporarily disabling the firewall.
