Constructor JTextField(int columns) doesn't throw IllegalArgumentException when
the number of columns is negative, but method setColumns(int columns) does.
               
Here is an example demonstratring the bug:
----------------Test.java---------------------
import com.sun.java.swing.*;

public class Test{

    public static void main(String[] args){
try{
JTextField field = new JTextField(-100);
System.out.println("IllegalArgumentException was not thrown by constructor");
}catch(IllegalArgumentException e){
System.out.println("IllegalArgumentException thrown by constructor");
}

JTextField field = new JTextField();
try{
field.setColumns(-100);
System.out.println("IllegalArgumentException was not thrown by setColumns() method");
}catch(IllegalArgumentException e){
System.out.println("IllegalArgumentException thrown by setColumns() method");
}
System.exit(0);
    }
}
---------------- output ----------------
IllegalArgumentException was not thrown by constructor
IllegalArgumentException thrown by setColumns() method
----------------------------------------
