mockito: Die Klasse [X] nicht bereit für den test

Nach der Migration von meinem JAVA EE app. (Spring-Web das model-view-controller (MVC) framework) von Ant auf Maven habe ich einige Fehler die Ausführung der Junit-test, der vor der migration waren in Ordnung arbeiten

org.powermock.api.mockito.ClassNotPreparedException: 
The class org.springframework.web.util.WebUtils not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or  method level.
