The method Identity.addCertificate must throw KeyManagementException
if there is a conflict between a certificate's public key and
identity's public key

According to the JDK 1.5.0 spec."
public void addCertificate(Certificate certificate)
                    throws KeyManagementException
.....
Throws:
KeyManagementException - if the certificate is not valid, if the
                         public key in the certificate being added
                         conflicts with this identity's public key,"

The example below reproduces this bug:
------------------test.java----------------
import java.io.*;
import java.security.*;
public class test extends Identity {

    public test(String name) { super(name); }

    public static void main(String[] av)
    {
        StubPublicKey key1 = new StubPublicKey("key");
        StubPublicKey key2 = new StubPublicKey("key");
 
        test id;
        try {
            id = new test("name");
            id.setPublicKey(key1);
        } catch(Exception e) {
            System.out.println("Failed: unexpected exception " + e);
            return;
        }
        
        StubCertificate cert = new StubCertificate(key2);

        System.out.println("Are keys equal: "
            + id.getPublicKey().equals( cert.getPublicKey() ) );

        try {
            id.addCertificate( cert );
            System.out.println("Failed: no KeyManagementException");
        } catch(KeyManagementException e) {
            System.out.println("Passed");
        }
    }
}

class StubPublicKey implements PublicKey {
    private String key;

    public StubPublicKey(String k) { key = k; }
    public String getAlgorithm() { return key; }
    public byte[] getEncoded() { return key.getBytes(); }
    public String getFormat() { return key; }
    public boolean equals(Object object) { return false; }
}

class StubCertificate implements Certificate
{
    private PublicKey key;

    public StubCertificate(PublicKey k) { key = k; }
    
    public void decode(InputStream stream)
            throws KeyException, IOException {}
    public void encode(OutputStream stream)
            throws KeyException, IOException {}
    public String getFormat() { return null; }
    public Principal getGuarantor() { return null; }
    public Principal getPrincipal() { return null; }
    public String toString(boolean detailed){ return null; }
    public PublicKey getPublicKey() { return key; }
}
------------------OUTPUT-------------------
Are keys equal: false
Failed: no KeyManagementException
