Description
Execute the attached TreeTableView program. 
"java.lang.IllegalStateException: Not a permutation change" exception is thrown. This happens only when selection is active. Also note that no exception is thrown in case of TreeView.
Comments
technically, the reason is an incorrect wasPermutated calculation in TreeModificationEvent: this.wasPermutated = added != null && removed != null && added.size() == removed.size() && added.containsAll(removed); that incorrectly sets the permutated flag for replacing a list with itself. Probably should query the change itself. But then, the whole event mapping needs a thorough overhaul as it routes disjoint changes from the real notification as a single one (pretty sure that we have bugs around that here, just can't remember - found one at least: JDK-8090563) The reason the error shows up in TreeTableView's selectionModel but not in TreeView's selectionModel is that the listener in the former handles the permutated case while the latter doesn't.
