/**
 * Returns the suffix of the url. The result should be identical to
 * that of calling getRootURLContext().getRemainingName(), but
 * without the overhead of doing anything with the prefix like
 * creating a context.
 *<p>
 * This method returns a Name instead of a String because to give
 * the provider an opportunity to return a Name (for example,
 * for weakly separated naming systems like COS naming).
 *<p>
 * The default implementation uses skips 'prefix', calls
 * CorbaUtils.decode() on it, and returns the result as a single component
 * CompositeName.
 * Subclass should override if this is not appropriate.
 * This method is used only by rename().
 * If rename() is supported for a particular URL scheme,
 * getRootURLContext(), getURLPrefix(), and getURLSuffix()
 * must be in sync wrt how URLs are parsed and returned.
 *<p>
 * For many URL schemes, this method is very similar to URL.getFile(),
 * except getFile() will return a leading slash in the
 * 2nd, 3rd, and 4th cases. For schemes like "ldap" and "iiop",
 * the leading slash must be skipped before the name is an acceptable
 * format for operation by the Context methods. For schemes that treat the
 * leading slash as significant (such as "file"),
 * the subclass must override getURLSuffix() to get the correct behavior.
 * Remember, the behavior must match getRootURLContext().
 *
 * <pre>{@code
 * URL                                     Suffix
 * foo://host:port                         <empty string>
