All Implemented Interfaces:

Task

public class UndeployAllSUsTask
extends AbstractLoggableTask

This task executes the undeployment process of a service unit, for each Service Unit included into the service assembly
Inputs : ServiceAssemblyLifeCycle, XMLResult
The task has got a mixed approach: it tries to do all the subtasks
and doesn't have the undo capability. But if the service assembly isn't over shutdown or unknown state,
to implement the JBI specification, it stops and thrown an exception to launch the undo process
