Awesome!

It is related to calling `clearSelection(int)` in a loop in
`CellBehaviorBase.java`, but these changes alone don't fix it. The solution is
pretty simple and passes all tests. Should I add that to this PR?
- // To prevent JDK-8123898, we make a copy of the selected indices
- // list first, so that we are not iterating and modifying it
- // concurrently.
- List<Integer> selectedIndices = new
ArrayList<>(getSelectionModel().getSelectedIndices());
- for (int i = 0, max = selectedIndices.size(); i < max; i++) {
- int selectedIndex = selectedIndices.get(i);
- if (selectedIndex < minRow || selectedIndex > maxRow) {
- getSelectionModel().clearSelection(selectedIndex);
- }
- }
+ getSelectionModel().clearSelection();
