I have 2 missing configuration parameters.
ConfigManager and ConfigManager2018 do not log the same warnings

Warnings of ConfigManager :

• The parameter 'workspaces.profile.list' is not valued. Configuration is not initialized.
• The parameter 'workspaces.member.added.send.notification' is not valued. Configuration is not initialized.

Warnings of ConfigManager2018 (only one instead of 2 and with a untranslated key)

• The parameter 'workspaces.member.added.send.notification' is not valid with value 'null' :
• plugin.core-ui:PLUGINS_CORE_UI_DEFAULT_VALIDATOR_MANDATORY
