A DESCRIPTION OF THE PROBLEM :
The removeLayoutComponent() method in the BasicSpinnerUI.SpinnerLayout class contains the following implementation:

public void removeLayoutComponent(Component c) {
if (c == nextButton) {
c = null;
}
else if (c == previousButton) {
previousButton = null;
}
else if (c == editor) {
editor = null;
}
}

Note that the 'true' condition for the first 'if' clause is a no-op. The statement should be:

nextButton = null;


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Problem is self-evident in source code.
