If method createContext() is invoked, the object is no longer serializable.
Object's field theContext is initialized with non-Serializable class
instance of java.awt.ColorPaintContext. This is causing the problem.
 
The test example to reproduce the bug:
-------------------------------------------------------------
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;

public class test {

  public static void main(String[] args) {
    try {
        java.awt.Color cobj = new java.awt.Color(255,255,255);
        cobj.createContext(
            new java.awt.image.IndexColorModel(
                8, 1, new byte[] {0}, new byte[] {0}, new byte[] {0}),
            new java.awt.Rectangle(1,1,2,3),
            new java.awt.Rectangle(3,3),
            new java.awt.geom.AffineTransform(),
            new java.awt.RenderingHints(null)
        );
        FileOutputStream ostream = new FileOutputStream("gold.tmp");
        ObjectOutputStream objos = new ObjectOutputStream(ostream);
        objos.writeObject(cobj);
        objos.close();
        System.out.println("OKAY");

    } catch (java.io.IOException e) {
        e.printStackTrace();
    }
  }

}

Test output:

java.io.NotSerializableException: java.awt.ColorPaintContext
        at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:1148)
        at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:366)
