Jan Haderka updated MAGNOLIA-3059:
----------------------------------
Fix Version/s: 4.5.7
(was: 4.3.x)
I think this issue should be gone by now. Needs to be re-evaluated before
closing as obsolete.
> Unable to replace implementation of the dynamically loaded class with its
> super class
> -------------------------------------------------------------------------------------
>
> Key: MAGNOLIA-3059
> URL: http://jira.magnolia-cms.com/browse/MAGNOLIA-3059
> Project: Magnolia
> Issue Type: Bug
> Security Level: Public
> Components: core
> Affects Versions: 4.3
> Reporter: Jan Haderka
> Assignee: Philipp Bärfuss
> Priority: Critical
> Fix For: 4.5.7
>
>
> Since the changes made to {{FactoryUtil}} and mechanism of class
> instantiation it is no longer possible to replace class implementation with
> its superclass at runtime.
> To reproduce the issue:
> # extend some existing class, e.g. {{URI2RepositoryManager}}
> # configure Magnolia to use extending class (in this case set
> {{/server/URI2RepositoryMapping/class}} to
> {{full.name.of.ExtendedURI2RepositoryManager}})
> # check that everything works fine with the extending class (e.g. try to
> display some page from website)
> # restart Magnolia to make to have it started with extending class
> # repeat step 3) (to see that everything still works)
> # change {{URI2RepositoryManager}} configuration back to use the original
> {{URI2RepositoryManager}} implementation
> # try to repeat step 3) ==> page loading fails with {{ClassCastException}}
