JSpinner gets spinning when mouse button is pushed down and the spinner is replaced with new one.

JSpinner gets spinning in the following scenario.

1. Spinner is created by using JSpinner.
2. To increase the value continuously, push the button of the spinner down
   and keep it being down. (Do not relese it.)
3. The spinner is replaced with new one.
   (Remove old one and make new spinner visible.)
4. getNextValue() does not stop. (It is spinning...)

I confirmed this problem occurs on Solaris and WindowsXP with Java 1.4.2_12.
This does not occur with Java 1.5.0.
