Here's the solution I've implemented and it works like a charm!

import java.net.*;
import java.util.*;
import java.util.logging.*;
import java.util.regex.*;

/**
 * Authenticator which keeps credentials to be passed to the requester
 * based on the concatenation of the authority and the URL that requires
 * authentication.
 * 
 * If the configured credentials are not found, the Authenticator will
 * use the embedded credentials if present.
 * 
 * Embedded credentials are in the form of 
user:password@host:port/<url-path>

    protected PasswordAuthentication getPasswordAuthentication() {

        if ((pa = authInfos.get(requesterInfo)) == null && (pa = getEmbeddedPA(getRequestingURL().getAuthority())) == null) {
            log.warning(String.format("No authentication information for \"%s\"", requesterInfo));
        }

        return pa;
    }

    public void setAuthInfos(Map authInfos) {
        this.authInfos = authInfos;
    }

    public void setEmbeddedAuthInfoPattern(String pattern) {
        this.embeddedAuthInfoPattern = Pattern.compile(pattern);
    }

    private PasswordAuthentication getEmbeddedPA(String authInfo) {
        if (authInfo != null) {
            Matcher matcher = embeddedAuthInfoPattern.matcher(authInfo);
            if (matcher.find()) {
                return new PasswordAuthentication(matcher.group(1), matcher.group(2).toCharArray());
            }
        }

    }
