Swing ChangeEvent occur twice

The existing source codes, which I try to debug, create the MyTabbedPane class from JTabbedPane.
Clicking the tab will generate the ChangeEvent twice inside the addChangeListener.
Why? Is that to make the ChangeEvent occur once only?


2011-10-11 09:02:00,211 DEBUG Langclient.modules.findPanel - addChangeListener index 1
2011-10-11 09:02:00,211 DEBUG Langclient.modules.findPanel - tabsCurrentIndex 1
2011-10-11 09:02:00,211 DEBUG Langclient.modules.findPanel - addChangeListener index 1
2011-10-11 09:02:00,227 DEBUG Langclient.modules.findPanel - tabsCurrentIndex 1

Are you sure that you haven't added your change listeners twice? I created a little SSCCE and I only get one event.
