Thanks for the clarification. So, this means that we should implement the same 
behavior in Mac and Linux as well - That is no event should be generated if the 
same item is selected! Correct?

Yes, correct.


Thanks,
Krishna

Hi Sergey,

The test with my changes will run on Linux and Mac as well, since basically I'm 
trying to select a different item, so that the event is always generated.

Yes, an event is generated if different items are selected, but the test was 
created to check a different use-case: when the same item is reselected. Before 
JDK-7171412 an event was expected, but after the fix no events should be 
generated, when the same item reselected. So in the test you need to select the 
same item an check that no events will be generated.

But, we should answer the question for JDK-8014503, so that the behavior is 
consistent on all platforms.

Thanks,
Krishna

If this was done intentionally then I suggest to revert the expectation of the 
test. But I think that the test will fail on lin/mac, because one more related 
bug JDK-8014503 was not fixed.
So we should run the test on windows only, until JDK-8014503 is not fixed.

Hi Sergey,

I think the current behavior is intentionally implemented in awt in Windows. I 
don't know how JDK-4902933 is marked as resolved, but there is a linked issue 
JDK-7171412. Here is the link to the patch that was pushed as fix for this 
issue, and we can see that there is an explicit suppression of event 
propagation in case of same index being selected again. Pasting the current 
code for reference:
MsgRouting AwtChoice::WmNotify(UINT notifyCode) {
       if (notifyCode == CBN_SELCHANGE) {
           int selectedIndex = (int)SendMessage(CB_GETCURSEL);

           JNIEnv *env = (JNIEnv *)JNU_GetEnv(jvm, JNI_VERSION_1_2);
           jobject target = GetTarget(env);
           int previousIndex = env->GetIntField(target,
selectedIndexID);

           if (selectedIndex != CB_ERR && selectedIndex != previousIndex){
               DoCallback("handleAction", "(I)V", selectedIndex);
           }

This is the reason why the test is failing.

Hope this clarifies.

Thanks,
Krishna

Hi, Krishna.

The basic problem is that, the Robot mouse move is moving to
position where item 0 is located (which is already selected), and selecting it.
Since this item is already selected, there is no new item selection
event generated, which is why the test fails.
As far as I understand the usecase which your describe was implemented 
intentionally in this test to verify the bug:
https://bugs.openjdk.java.net/browse/JDK-4902933

Did you check what is the reason of behavior change?
