A DESCRIPTION OF THE PROBLEM :
ChangeListener for TableView.focusWithinProperty() is not always called. It seems that it depends on the row selected.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided code. Click alternately on the right and left tables. You will notice that if you click on the rows below, the ChangeListener is triggered. If you click on the rows above, the ChangeListener is not triggered.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
ChangeListener for TableView.focusWithinProperty() must be always called when table gets focus.
ACTUAL -

CUSTOMER SUBMITTED WORKAROUND :
As focusWithinProperty for the parent node of the TableView will not work use TableView.focusedProperty instead

NOTES:
1. TAB/shift-TAB key presses also fail to change focusWithin property
