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
Components: core
Affects Versions: 4.3 M1
Reporter: Jan Haderka
Assignee: Philipp Bärfuss
Priority: Critical
Fix For: 4.3
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}}
