MyEclipse Unable to create servers view: Could Not create the View:an unexpected exception was thrown

Just opened MyEclipse today, found that the servers view could not be opened, showing: Could not create the View:an unexpected exception was thrown. Such as:

After checking the Internet, the solution is as follows:

In the error there is an at com.genuitec.eclipse.ast.deploy.core.Deployment, to the. Metadata\.plugins\org.eclipse.core.runtime\ under the working space. Settings directory below found a file named Com.genuitec.eclipse.ast.deploy.core.prefs, open the file, which is the original project information, so it will be reported java.lang.NullPointerException error. Delete this file and restart MyEclipse to resolve the issue.

Analysis: It is possible that the previous close item in the package explorer was closed without being removed from Tomcat.
