I have a frame on which i have added some awt components. I have set one button to setFocusable(false), When i click the setFocusable(false)button the components on the frame gets removed one by one except setFocusable(false) button & a list & then later i am checking for the focus owner & focus window.
On windows it gives Button1(first component) & next time when click the button i am getting frame as the focusowner & focus window. But on solaris , i am getting Button1 as the focus owner & next time when i click i am getting choice as the focus owner( second component ) & frame as focus window. Where choice is removed. So the removed component can't be a focus owner.

I tried an another scenario(Scenario #2) instead of removing all the components(see comment in actionperformed() ) , i just removed first two components & left last two components one focusable(list) & one nonfocusable component(button). But Still the problem can be seen. i,e i expect focus to be on list , but i can see the above described results.

I tried with an another scenario(Scenario #3), When the frame is visible , press tab so that second component may receieve the focus & when i press the nonfocusable button. the list receives the focus as expected.

Step to reproduce for Scenario1:
--------------------------------
1) Run the attached program.
2) Click on "Button2". Observe that components gets removed & see the console that "choice is the focus owner & its opposite component is "button1". If you see the same then the bug is reproduced.

Step to reproduce for Scenario2:
--------------------------------
Note:- Comment the line in actionPerformed line ( i have given the comment in the testcase).
1) Run the attached program.
2) Click on "Button2" . Observe that List dn't have focus. If you see the same then the bug is reproduced.

Step to reproduce for Scenario 3:
--------------------------------
Note:- Comment the line in actionPerformed line ( i have given the comment in the testcase).
1) Run the attached program.
2) Press "Tab" . Now choice gain the focus.
2) Click on "Button2" . Observe that List have focus. This is the correct behaviour.

I tested this in jdk1.5.0 to jdk 1.7.0.
