Bug 168281

Create simple Maven Project and open pom.xml .Right-click in editor on <version> line to invoke context menu,select
Insert Code and select Plugin. Write surefire into name field,select appropriate jar and click OK.
Exception will appear (I expected either automatic insert of plugin to correct line or error message,not exception):
