解决办法：
找到目录 eclipse\workspace\.metadata\.plugins\org.eclipse.ui.workbench 下面的 workbench.xml文件，删除在XML节点
<mruList>
</mruList>
之间的所有内容，然后运行Eclipse，测试是否已经解决。
如果问题还是存在，那么请在workbench.xml文件中查找最后一次（也就是出错之前）运行的程序名称，例如我的是运行的 XXXXX.sql 出现的问题，于是查找
XXXXX.sql 字符串，将有关的部分都删掉，然后在继续运行。
即可。
再不行的话，把之前出错的那个project从你的workspace中先拷到其他地方，再打开eclipse。
