Mauro Talevi commented on JBEHAVE-492:
--------------------------------------

To do that, we'd loose the nice abstraction that we have wrt multiple DI 
containers.  And not at all easy given the current design.

Rather, it seems to me that we should focus on making the configuration 
thread-specific.

Passing the classes instead of the instances is not necessarily the only way to 
achieve the stated goal.

> 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.
