我在eclipse IDE 3.2中经常出现以下错误,如何从这些OutOfMemory中保存应用程序？

在我编写的应用程序中,我在特定计算机上有一个java.net.SocketException:
java.net.SocketException:协议族不支持的地址族:connect
此特定计算机运行Windows 7 32位并通过本地连接(以太网)连接到Internet.该应用程序在其他计算机上正常运行,Windows 7和Windows 8,通过本地连接或Wi-Fi连接,所以我实际上不确定问题是程序化的.我试图检查本地连接的协议,但我没有看到任何问题.有人可以帮我理解是什么问题吗？为什么抛出这个异常？
我正在使用Eclipse Kepler的新副本,但我无法找到市场.我知道它通常在"帮助"下,但它不在那里.
有没有选项让它再次可见？
Mayby很高兴知道,我正在研究Ubuntu 12.10
我在ubuntu 13.04 64位上安装了eclipse kepler 64位.
当我尝试打开日食市场时,我收到以下错误:
Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Cannot complete request to http://marketplace.eclipse.org/catalogs/api/p: Content is not allowed in prolog.
Cannot complete request to http://marketplace.eclipse.org/catalogs/api/p: Content is not allowed in prolog.
Content is not allowed in prolog.
Cannot complete request to http://marketplace.eclipse.org/catalogs/api/p: Content is not allowed in prolog.
Content is not allowed in prolog.
然后我检查了日志,发现以下内容:
eclipse.buildId=4.3.0.M20130911-1000
java.version=1.7.0_25
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_IN
Framework arguments: -vm /usr/lib/jvm/java-7-openjdk-amd64/jre -product org.eclipse.epp.package.jee.product
Command-line arguments: -os …我已经下载了最新的eclipse版本,eclipse kepler.
但是当我尝试在eclipse中访问Marketplace或尝试为Android安装ADT插件时,它给了我这个令人毛骨悚然的错误,这让我发疯:
Cannot open Eclipse Marketplace
