several instances need to be created. - In the ThreeMFWorkspaceReader we need to create some temporal instances of Preferences that makes it not singleton anymore. - The current preferences are kept in the Application class and so all the calls to the preferences are changed to get the preferences from Application. - The method getInstance in Preferences is kept as deprecated since some external plugins.
