Oracle ADF client usage of an Application Module

In this period very often someone ask me how to avoid usage of deprecated API findDataControl used usually in old implementation 

MyApplicationModuleImpl am= (MyApplicationModuleImpl) BindingContext.getCurrent().findDataControl("MyApplicationModuleDataControl").getDataProvider();

you can use createRootApplicationModuleHandle as follow (official suggestion)

  ApplicationModuleHandle handle =
   Configuration.createRootApplicationModuleHandle("mypkg.AppModule", "AppModuleShared");
  ApplicationModule sharedAM = handle.useApplicationModule();
  ...
  Configuration.releaseRootApplicationModuleHandle(handle, false);

The preferred way to have a business component access is for me the pageDefUsage. Migrating an old application you can have many occurrency of findDataControl to substitute.

I avoid the usage of createRootApplciationModule method because in my experience at runtime in seams to be slow.
