In the method BasicTreeUI$Actions.moveSelectionToParent
ensureRowsAreVisible must be called only if index != -1:
--- 4181,4188 ----
                  int newIndex = ui.getRowForPath(tree, path.getParentPath());
                  if (newIndex != -1) {
                      tree.setSelectionInterval(newIndex, newIndex);
                      ui.ensureRowsAreVisible(newIndex, newIndex);
                  }
              }
          }
