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)

FULL OPERATING SYSTEM VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
I am attempting to force the JSpinner to select its text
when receiving a focusGained notification. I extract the
JTextField from the spinner and call the selectAll()
method. Printing out the selected text works correctly.
However, in the GUI the text is not selected.

I have debugged into the swing source, and I believe that
after my FocusAdapter executes, the text in the JSpinner is
validated (the text is apparently removed and re-inserted)
which annuls the selection made in my FocusAdapter.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and execute the included source
2. Tab to the JSpinner
3. Notice that the selection output in the debug statement
indicates that text is selected.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected result: When tabbing to the JSpinner, the text
should become selected.

Actual result: When tabbing to the JSpinner, the text is
not selected. The caret is set on the left-hand-side of
the right-aligned text.

This bug can be reproduced always.
