关于fedora 20中Eclipse不能启动的问题解决

　　我安装了fedora 20，并慢慢的开始适应了它，从windows平台向linux平台迁移是一件不容易的事，但这样做也是有回报的，至少不用安装杀毒软件了，机器也是运行很愉快的。而且对于一个注定要终身不离电脑的人来说，没有比linux更好的系统可用于慢慢研究了，从此人生又多了一件乐事。但起步总还是艰难的，因为对一个东西不熟悉的时候，就很容易碰到一些看似棘手的问题，这不，现在就有这么一个，刚装上了新系统，以root用户身份登录，想打开个eclipse来自我满足下，就遇上事儿了，桌面蹦出这个错误画面：

在文件中将其注释掉就好了，像这样:

保存并重启eclipse就可以正常打开了，像下面一样：

为了这文章更容易搜索，我把错误信息变成文本列于下面，读者可以自行忽略：
