与本地主机的HTTP连接失败

Question

I have a Java application that makes REST requests to a Jetty server.

It works if I connect to the server with a real DNS name but I get the following exception when I want to make requests to my local testing instance on localhost:

Caused by: com.sun.jersey.api.client.ClientHandlerException: java.io.IOException: Stream closed

Requests in the browser and with my REST tool work.

I got it to work when I use the IPv6 address for localhost: https://[0:0:0:0:0:0:0:1]/

It always worked for me with localhost. Is it possible that some Java or Windows 7 update changed a default setting so it uses IPv6 instead?

What can I do to make localhost work again and do I need to be worried that this might cause a problem on other PCs when they want to connect to our real server?

I would like to be IPv4 and IPv6 compatible.

edit: here is my hosts file (it is unedited)

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost

Answer 1

So I finally found the problem. Apparently Skype uses port 80 and 443 as alternative ports. As soon as I quit Skype everything worked.

WebApp accessible via localhost but not 127.0.0.1

It probably worked with the IPv6 localhost address because Skype doesn't bind to that one.
