FULL PRODUCT VERSION :
java version "1.4.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-b92)
Java HotSpot(TM) Client VM (build 1.4.0-b92, mixed mode)


Observed on RedHat Linux 6.1, JDK 1.4.0 and 1.3.1_02, kernel
2.2.12, Enlightenment window manager. Same on Win2K/1.4.0.

A DESCRIPTION OF THE PROBLEM :
In Metal L&F, I would expect that the gesture
Ctrl-Shift-Click on a list or tree would extend a selection
from the previously selected item (like Shift-Click does)
without clearing other disjoint selections (like Ctrl-Click
does). At least on Windows, this is normal behavior, and I
expected it to work in Metal L&F as well, but it did not.

Compare NetBeans/Forte for Java bug, closed as a Swing
problem:

http://www.netbeans.org/issues/show_bug.cgi?id=3714

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run demo program. Click "one" in the list. Ctrl-click
"three". Ctrl-shift-click "five".

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected: one, three, four, and five are selected. Actual:
one, three, and five are selected, but four is not - same as
if the last step had been to ctrl-click "five" without the
Shift modifier.

This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.*;
public class TreeSelectionTest {
    public static void main(String[] args) {
        JTree tree = new JTree(new Object[] {
            "one",
            "two",
            "three",
            "four",
            "five",
        });
        JList list = new JList(new Object[] {
            "one",
            "two",
            "three",
            "four",
            "five",
        });
        JFrame f = new JFrame("Test tree selection");
        f.getContentPane().add(new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, tree,
list));
        f.pack();
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setVisible(true);
    }
}

CUSTOMER WORKAROUND :
If no long ranges (only short ones) need be selected, just
use Ctrl-click for every item. If only one long range need
be selected, do it first with Shift-click, then add
individual items with Ctrl-click. If more than one long
range needs to be selected, you are out of luck.
