/**
Inconsistent behavior on control-click in JTable.

In a JTable, when multiple interval selections are NOT allowed, the
behavior on control-click is inconsistent. It alternates between
two modes.

  To see an example, run this program. Select a cell. Then, hold down
the control key and repeatedly click on any other cell IN THE SAME ROW
OR COLUMN.

Instead of getting the same behavior each time, the behavior
alternates between two different modes. Sometimes the new cell will
get an outline, then the next clicked-cell gets filled with the
selection value. The next one gets the outline again.

If the new cell doesn't share the same row or column, the behavior is
consistent, in that the selection color fills the cell. This is what
we should always see, regardless of where the click occured.

Although the behavior differs slightly, the bug shows up when the
selection mode is single-selection, or single-interval-selection.

This bug shows up under JDK 1.2.2 and JDK 1.3 RC1.

There is a similar RFE (4196969), but this strange behavior should be
considered a bug.
