#1597|http://hudson.magnolia-cms.com/job/magnolia_main-trunk/1597/]
(fixed test for MAGNOLIA-3190)
MAGNOLIA-3190:
* MagnoliaObjectWrapper now holds a reference to FreemarkerConfig instead of
usings its singleton.
* Freemarker instanciates MagnoliaObjectWrapper instead of using
ComponentsProvider
* Removed MagnoliaObjectWrapper property from {{mgnl-beans.properties}} : if
you used a custom MagnoliaObjectWrapper, you'll need to subclass and configure
your custom FreemarkerConfig instead.

> Freemarker: incomplete configuration of sharedVariables results in
> StackOverflowError
> -------------------------------------------------------------------------------------
>
> Key: MAGNOLIA-3190
> URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3190
> Project: Magnolia
> Issue Type: Bug
> Components: freemarker
> Affects Versions: 4.3.1
> Reporter: Grégory Joseph
> Assignee: Grégory Joseph
> Fix For: 4.3.x
>
>
> While configuring {{/server/rendering/freemarker/sharedVariables}}, one can
> enter an endless loop, quickly resulting in a StackOverflowError; this
> happens, for instance, when adding a node under sharedVariables, and not
> filling it in it with a class attribute. The error only shows up on startup,
> so if the configuration is complete and correct before restarting Magnolia,
> one should be safe.
> The reason this happens is because {{FreemarkerConfig#addSharedVariable}}
> needs an instance of {{ObjectWrapper}}, and in turns, our
> {{MagnoliaObjectWrapper}} needs an instance of FreemarkerConfig, which it
> gets via {{Components}} Since Content2Bean calls addSharedVariable() before
> FreemarkerConfig is registered in {{Components}}, this results in a stack
> overflow.
