fix is very simple 

- Go to Application resource -> Descriptors-> META-INF -> weblogic-applications.xml 

 see there must be an entry like below

<listener>

    <listener-class>oracle.webcenter.lifecycle.listener.FeatureMetricApplicationListener</listener-class>

  </listener>

You just need to remove this listener entry that's it !!
