Presumably your states map to the following ICCCM states:

Withdrawn:
 A. invisible and iconified          
 B. invisible and deiconified

Iconic:
 C. visible and iconified

Normal:
 D. visible and deiconified

State transitions are covered in the ICCCM but a quick summary
I think is right:

 A -> B:  internal to Java app, no interclient communication
 A -> C:  map window with WM_STATE set to Iconic
 A -> D:  map window normally, WM_STATE unset

 B -> A:  internal to Java app
 B -> C:  map window with WM_STATE set to Iconic
 B -> D:  map window normally, WM_STATE unset

 C -> A:  withdraw window
 C -> B:  withdraw window
 C -> D:  map window

 D -> A:  withdraw window
 D -> B:  withdraw window 
 D -> C:  iconify window
