上周突然之间，一个javascript文件将不再在比较编辑器中打开。
- 我正在运行最新的火星月食
- 我正在运行最新的Subclipse
- 我与repo同步，并查看更改的文件
- 当我双击或选择比较时，我会看到一个空白的白色页面，上面写着"正在初始化…"，或者看到一个灰色的空白页面
- 它只包含一个特定的text.js文件。。。项目中的所有其他文件和其他项目的差异都很好
- 该文件为37880字节
- 我已经删除了subversion设置文件，并重新创建了它们
- 我已经检查了首选项并忽略空白
这只是一个文件。。。它是node.js项目的主文件。它过去的diff很好，上周突然间，这个文件将不再diff，并引发了这个异常。
当我查看日志时，我看到以下异常：

我没有解决方案，但我遇到了同样的问题，并找到了解决方法。我在"General"->"compare/Patch"下的eclipse首选项中关闭了"Open structure compare automatically"。然后我就可以在比较编辑器中打开文件了。
这看起来像Eclipse错误390913，它已经打开了一段时间，但似乎没有任何进展。
