以前从没遇到过这种问题,发现自重装系统后,就开始触发这个bug了.
从error-log等视图里点击打开的java文件或者xml文件时,出现”unhandled event loop exception”错误,出错信息如下:

我的解决过程:网上搜索后找到这个.
解决方法: 重装了下jdk(没有重启机器)还是无效.然后,修改了workspace,重启机器,ok.发现,很多问题都可以通过修改workspace来解决,建议一个工程一个workspace. 上述方法无效！！ Google下发现好像是打开.java的默认编辑器在win7x64位的笔记本上有问题，解决方法：help->install new software，从http://download.eclipse.org/windowbuilder/WB/release/R201309271200/4.3下载windowbuilder，并把其设置为默认的.java编辑器。重启Eclipse后切换回.java文件时不出bug了,但是切换回.xml文件还是会触发这个bug。
最后的终极解决方法:
更新 Win7 ! ok,问题解决!
(windows update了下win7,搞定！！所以：直接进行windows update，安装关于security的补丁！)
