Hi Prasanta,

   fix looks fine to me.

 > Hi All,
 >
 > Please review a fix for an issue seen whereby VK_ENTER is not handled 
when popup is visible for a comboBox.
 >
 > This issue is regressed because of the JDK-8067986 fix where a check 
is done upfront whether to accept this key VK_ENTER by checking if 
InputMap for VK_ENTER is set up or not.
 >
 > The fix did not take into account if popup is visible or not. If 
popup is visible, it should irrespectively accept and allow 
actionPerformed() to be executed.
 >
 > Fix is updated to check for popup visibility. The closed test and 
8067986 regression test both pass with this change.
