WAS 8.0.0.9, Cannot Build FileRegistrySample.java File, missing com.ibm.websphere.security

I am trying to create a "Standalone custom registry" for WAS so it can be used in conjunction with Asset Manager.  I have been reading from the following links:

There is a sample class, "com.ibm.websphere.security.FileRegistrySample".  In following the directions to build it, I am getting the following error:

FileRegistrySample.java:19: package com.ibm.websphere.security does not exist
import com.ibm.websphere.security.*;
^
FileRegistrySample.java:31: cannot find symbol
symbol: class UserRegistry
public class FileRegistrySample implements UserRegistry {
                                           ^
FileRegistrySample.java:50: cannot find symbol

I have loaded the WAS 8.0.0.9 Supplements which I thought would include this java file.  I know you are not supposed to use the Sample for production, but I am just trying to use this as baseline, get it to build and work and then I could modify it accordingly.

Any help is appreciated.
