A DESCRIPTION OF THE PROBLEM :
When an instance of JSpinner with a default editor is deserialized, the associated action map is not correctly restored, so when an arrow button is pressed or an up/down key is hit on the deserialized component, nothing happens.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
create a JSpinner.
serialize the JSpinner to a stream.
deserialize the JSpinner from the stream.
add the deserialized JSpinner to a frame.
make the frame visible.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
when an arrow button is pressed or an up/down key is hit on the deserialized JSpinner, the value in the text field should increase/decrease.
ACTUAL -
when an arrow button is pressed or an up/down key is hit on the deserialized JSpinner, nothing happens.

REPRODUCIBILITY :
This bug can be reproduced always.
