Swing 1.0.2 under JDK 1.1.6:

In circumstances where ListSelectionModel.clearSelection()
is called, listeners are messaged with ListSelectionEvent
firstIndex and lastIndex = -1; yet misleadingly this isn't
documented.

DefaultListSelectionModel: breaks SINGLE_SELECTION in setLeadSelectionIndex

Assuming a DefaultListSelectionModel in mode SINGLE_SELECTION that
once had a selection which was removed we get multiple selections
by setting the lead twice (jdk117, swing111beta1):

Example:

import javax.swing.*;

public class TestSingleSelection {
  DefaultListSelectionModel selection = new DefaultListSelectionModel();

  public TestSingleSelection() {
    selection.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
    selection.setSelectionInterval(0, 0);
    // without removing, everything's ok
    selection.removeSelectionInterval(0, 0);
    selection.setLeadSelectionIndex(2);
    System.out.println(selection.getMinSelectionIndex() + " " +
selection.getMaxSelectionIndex());
    selection.setLeadSelectionIndex(3);
    System.out.println(selection.getMinSelectionIndex() + " " +
selection.getMaxSelectionIndex());
  }

//---------------------------Main

public static void main(String[] args) {
new TestSingleSelection();
}

} // end class TestSingleSelection
