These terms are not OFBiz specific, you can see examples of these in
any OO (or other types of) code.
Also it is hard to make a formal distinction among them, because they
overlap most of the time but basically (my understanding is that)
- helper is a class with common (static) methods, used from different
classes(because the methods cannot be put to one or the other class
they are extracted to a helper class).
- workers sometimes are used as helper and sometime to indicate a
class that is executing a task/thread
- wrapper is a little bit different than the previous two, because it
is supposed to wrap another object, so it has a state - the wrapped
object and enrich its functionality(decorator), or provide a
simplified interface(facade) or change the interface(adapter)
