Mauro Talevi commented on JBEHAVE-492:
--------------------------------------
Sorry, still no wiser about this use case :-( What do you mean by "initial
instance"?
> ConfigurableEmbedder.addSteps(..) should take classes not instances.

> Why? There's an instance that's made during the setup of a suite (refer
> EtsyStories). If you are running in multi-threaded mode, that **initial**
> instance is **never** used during the running of scenarios.
> In multi-threaded mode, there's a constructor for BasePage that takes a
> WebDriverProvider. When it is passed in during the primordial instantiation
> phase, no WebDriver has been initialized. We don't want to do that of course
> because (a) we know this **initial** instance is going to be garbage
> collected and never used, and (b) on SauceLabs at least it would result in
> browser opening in the cloud then closing (or maybe not closing, but never
> used; I'm not sure).
> JBehave does not actually need the **initial** instance. I believe this is
> provable. Instead it could perfectly well use the class definition without
> the instance ref somehow.
> Proposal: Long overdue, I think, but could for 4.x we shift to using
> class-defs. Either rework CandidateSteps to hold a Class rather than an
> instance. Or further do a away (move the logic elsewhere) with
> CandidateSteps, and use the POJO Step's class-def directly.
