Detecting problems with the Plugins loading behavior

For a Plugin to be loaded:

• The Plugin must have a Manifest declaring its main class and also possibly other properties
• If the Plugin has a PluginType Manifest property, this type must be allowed by the application
• If the application ID returns a not null value, the PluginClass Manifest property must echibit the application ID
• The Plugin Plugin.register(MDIApplication appli) method must not throw an Exception

Understanding where a problem may come from

By default the Plugins loading process is silent, but it is possible to log the Plugins initialization.
