If one wants to write his own WorkflowDelegate extending the AbstractWorkbenchDelegate, such as
public class HelloWorldWorkflowDelegate
he needs to specify the WorkflowConfigurationType and WorkflowType as type parameters. To be able to use the standard Workflow class, as shown above, the class loader needs to access classes from org.eclipse.ui to resolve a valid type hierarchy in the de.uka.ipd.sdq.de.workflow.workbench plugin.
To ensure this, the plugin de.uka.ipd.sdq.de.workflow.workbench should reexport the dependency to the plugin org.eclipse.ui.
Otherwise you will get an error such as no valid type hierarchy.
