#3 ClosableTabbedPane fails when closed using Java 6

[Greg Kopff]

When using Java 6, the ClosableTabbedPane fails with a ArrayIndexOutOfBoundsException when you try to close it using its [X] button.

Exception in thread "AWT-EventQueue-0"
java.lang.ArrayIndexOutOfBoundsException: 1 >= 1

Well, I commented out the call to setButtonVisible() which hides the old index button (see below) ...

private class SelectionHandler implements ChangeListener
{
int oldIndex = -1;

public void stateChanged(ChangeEvent e) {
// GSK: commented out these three lines for JDK6
// if (oldIndex != -1) {
// setButtonVisible(oldIndex, false);
// }
oldIndex = getSelectedIndex();
if (oldIndex != -1) {
setButtonVisible(oldIndex, true);
}
}

}

This fixes the array index out of bounds exception and doesn't appear to adversely affect the operation of the tabs.
