A DESCRIPTION OF THE PROBLEM :
TableView.getSelectionModel().getSelectedItems() observable list incorrectly reports the list changes when a FilteredList is used. For example, it can report to registered listeners that 3 elements were removed while the list contained only one before the change.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the attached code and you'll notice that even though the list contained only one element, after the list is cleared, it reports that 3 elements were removed.
