JDK-1.2.2-N fails to pass SignatureTest of JCK-1.2a that reports
following error messages:

Missing Fields
--------------

java.util.HashMap:  field public static final long serialVersionUID
java.util.LinkedList:                   field public static final long serialVersionUID
java.util.TreeMap:  field public static final long serialVersionUID

STATUS:Failed.3 errors

The problem is caused with "serialVersionUID" field inherited from 
java.io.Serializable and hidden by non-public field with the same name in the
following classes:

java.util.HashMap,
java.util.LinkedList,
java.util.TreeMap classes.

As result the same Java program is successfully compiled
under JDK-1.2 but JDK-1.2.2-N compiler reports compile-time errors.

The example below demonstrates that.
