If method setAltNameCtx() is invoked with a non-Serializable parameter,
the object is no longer serializable.
For example, it could be invoked with instance of javax.naming.InitialContext.
In this case object's field 'altNameCtx' will be initialized with
non-Serializable class instance of javax.naming.Context. This causes 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 {
        javax.naming.CannotProceedException obj =
            new javax.naming.CannotProceedException();
        obj.setAltNameCtx(new javax.naming.InitialContext());

        FileOutputStream ostream = new FileOutputStream("gold.tmp");
        ObjectOutputStream objos = new ObjectOutputStream(ostream);
        objos.writeObject(obj);
        objos.close();

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

}
-------------------------------------------------------------
Test output:

java.io.NotSerializableException: javax.naming.InitialContext
        at java.io.ObjectOutputStream.outputObject(ObjectOutputStream.java:1148)
        at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:366)
