> h4. Steps to reproduce
> - start Oak repository in OSGi setup with additional required (custom)
> services that are passed to various security modules as config parameter such
> as e.g. {{RestrictionProvider}}, {{UserAuthenticationFactory}},
> {{AuthorizableNodeName}} or {{AuthorizableActionProvider}}
> - verify that the security setup contains the custom configurations
> - now, force a re-registration of the {{SecurityProvider}} by changing a
> referenced/required security service, which is not associated with the custom
> configuration as specified in the initial setup
> - once completed any {{SecurityConfiguration}}, that is associated with
> custom configuration params such as the examples listed above will no longer
> have the corresponding params set.
> h4. Finding step by step
> - {{SecurityProviderRegistration}} waits until all configured required
> service references have been registered and all non-dynamic references have
> been resolved.
> - Once everything is resolved the {{SecurityProviderRegistration}} looks as
> expected including all configuration parameters
> - {{SecurityProviderRegistration}} now starts creating a new
> {{SecurityProvider}} instance with all the unary and required module
> references.
> - During this step it also calls {{initializeConfiguration}} in order to have
> the modules populated with additional stuff from the
> {{SecurityProviderRegistration}} and it's here we have IMHO a bug: The
> {{initializeConfiguration}} will push the params from
> {{SecurityProviderRegistration}} to the {{SecurityConfiguration}}, while at
> the same time trying to merge params defined directly on the
> {{SecurityConfiguration}}.
> h4. Explanation
> In a plain Java setup as it was initial designed for the
> {{SecurityProviderImpl}}: The 'local' params from {{SecurityConfiguration}}
> need to take precedence over those present in {{SecurityProvider}}.
> However, In our new, pure Osgi setup, where there is no such
> mixed-param-setup, we would need a mandatory overwrite of e.g.
> {{RestrictionProvider}} (s) or {{AuthorizableActionProvider}} (s), because
> the _old_ values in the {{SecurityConfiguration}} had not been provided by
> it's own config but as a matter of fact refer to the old values of the
> {{SecurityProviderRegistration}}, which got unregistered and thus are stale
> service references.
> h4. Potential Fixes
> In any case we must have a unit-test that illustrates the problem and allows
> us to verify that whatever fix we apply actually addresses the problem. I
> will try to provide that today.
> h5. Variant 1
> Looking back my feeling is, that we should have moved all those extra-params
> that get pushed to the {{SecurityConfiguration}} as references to the
> modules. Not sure if/how that is feasible at the current state without
> risking too many compatibility issues and regressions.
> h5. Variant 2
> Since we no longer have a mixed java/osgi setup since the introduction of the
> {{SecurityProviderRegistration}} and removed the OSGi-annotations from the
> old (now pure java) {{SecurityProviderImpl}}, we might consider just changing
> the following call in {{SecurityProviderRegistration}} from:
> {code}base.setParameters(ConfigurationParameters.of(parameters,
> base.getParameters()));{code}
> to
> {code}base.setParameters(ConfigurationParameters.of(base.getParameters(),
> parameters));{code}
> and thus actually doing what we intend to do: replace the existing entries in
> the {{SecurityConfiguration}} by the new ones.
