当在对象生命周期的哪个点使用匿名内部类作为PropertyChangeListener时,是否收集了类垃圾？收回包含类(SettingsNode)后？我应该在包含类(SettingsNode)的终结器中显式删除PropertyChangeListener吗？

public class SettingsNode extends AbstractNode
{
    public SettingsNode(Project project, ProjectSettings projectSettings)
        throws IntrospectionException
    {   
        // use an anonymous inner class to listen for changes
        projectSettings.addPropertyChangeListener(ProjectSettings.PROP_NAME,
            new PropertyChangeListener()
            {
                @Override
                public void propertyChange(PropertyChangeEvent evt)
                {
                   // handle event
                }
            });
     }
}
