A DESCRIPTION OF THE PROBLEM :
I am using JFrame's setDefaultLookAndFeelDecorated and set it is true. While Changing the LookAndFeel FROM Metal to Windows/Motif LookAndFeels in Runtime by the user, title bar of the JFrame is not visible, so i can't minimize/resize/close the JFrame. But i closed and reopen the application the problem is solved by using default LookAndFeel Decoration (Windows)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Just change the look and feels I provided with my program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
LookAndFeel needs to be changed normally, I need my title bar on my JFrame
Title bar will not visible after changed to Motif/Windows Look And Feel

REPRODUCIBILITY :
This bug can be reproduced always.
