      A DESCRIPTION OF THE PROBLEM :
      Dead keys followed by space doesnt generate a character in swing
      components on Linux if a on non US key boards is used.
      I have experienced the bug with a Swedish keyboard
          
          
        To write a tilde character I write a tilde character on a Swedish
      keyboard I would press "ALT-GR-tilde" followed by "space". When I
      do this no character seams to be written to swing text components
      like JTextField and JTextArea.
          
          
      Since tilde is used in URL, this bug prevents the use of java on
      Linux for internet related GUI applications.
          
      Problems with dead keys on non US keyboards have bin around for
      almost two years. Bug 4379138 have bin closed as fixed. But this
      related problem with space after dead keys still remain. Or
      is it the same problem?


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Use a Swedish keyboard (Any non US Keyboard where ALT, and ALT-GR
         is two distinkt keys could perhaps verify be uset to verify bug,
         but I have no keyboards to test that)
        
        
      2. Make sure that you have configured the InputDevice section of your
         /etc/X11/XF86Config-4 to look like:
        

        
      Section "InputDevice"
              Identifier "Keyboard0"
              Driver "keyboard"
              Option "Xleds" "1 2 3"
              Option "XkbRules" "xfree86"
              Option "XkbModel" "pc104"
              Option "XkbLayout" "se"
      EndSection
        
        
      3. Compile and run the following program:
       
        
        
      4: Type the key sequence [Alt Gr]-[tilde] followed by [space]
        
        


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      Expected result:
       A tilde character should have turned up in the JTextField.
       But it doesn't.


      REPRODUCIBILITY :
      This bug can be reproduced always.
