The OP created a pretty good SSCCE here and for that purpose pack() 
would not demonstrate what he wanted to show.  The only possible problem 
he would have with the LayoutManager is too little space to display his 
example.  Most of the time, having extra space in a frame isn't going to 
cause any display problems.  I think he can be forgiven for not packing 
this time (as I hope I can for my example :-).
