public static Class loadClass(String name)
does not look at property "java.rmi.server.codebase" if it is
changed. For example if loadClass(String) has been called 2 times and
before the second time property "java.rmi.server.codebase" has been
changed - it will still be attempted to load class from codebase URL
specified by the "old" property.
See example:

=== T.java ===
import java.rmi.*;
import java.rmi.server.*;
import java.net.MalformedURLException;

public class T {
    static String root = "file:///home/dsv/tmp/";
    // should be changed ^^^^^^^^^^^^^^^^^^^^^^
    static String property = "java.rmi.server.codebase";
    static Class cl = null;

    static void loadLoadMe(String from) {
        try {
            System.setProperty(property, from);
            System.out.println(property+"="+System.getProperty(property));
            cl = RMIClassLoader.loadClass("LoadMe");
            Object obj = cl.newInstance();
            System.out.println("LoadMe object says: " + obj.toString());

        } catch (Exception e) {
            System.out.println(e);
        }
    }

    public static void main(String[] argv) {
        System.setSecurityManager(new RMISecurityManager());
        loadLoadMe(root+"LoadMe1/");
        loadLoadMe(root+"LoadMe2/");
    }
}

=== LoadMe.java #1 === (should be in subdir LoadMe1/)
public class LoadMe {
    public String toString() {
        return "LoadMe1";
    }
}

=== LoadMe.java #2 === (should be in subdir LoadMe2/)
public class LoadMe {
    public String toString() {
        return "LoadMe2";
    }
}

=== output ===
