启动Eclipse时,在loading workbench时很快就闪退，反复启动几次都是这种情况，关机重启后还是出现这种情况，并且每次闪退后都提示查看\workspace\.metadata\.log ，进入该目录中，发现有如下异常信息记录：

!ENTRY org.eclipse.e4.ui.workbench.swt 4 2 2016-08-23 08:42:49.516

出现该问题的原因是：由于项目没有正常关闭运行而导致"workbench.xmi"中的"persistedState"标签还保持在运行时的配置造成的。

解决办法：

找到<workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi"文件，将其删掉，再重启Eclipse，恢复正常。
