Class JBossRMIClassLoader

java.lang.Object
  java.rmi.server.RMIClassLoaderSpi
      org.jboss.system.JBossRMIClassLoader

public class JBossRMIClassLoader
extends RMIClassLoaderSpi

An implementation of RMIClassLoaderSpi to workaround the proxy ClassCastException problem in 1.4

THIS IS A HACK!

Sun's implementation uses the caller classloader when unmarshalling proxies. This is effectively jboss.jar since that is where JRMPInvokerProxy lives. On a redeploy the new interfaces are ignored because a proxy is already cached against the classloader.

This class ignores Sun's guess at a suitable classloader and uses the thread context classloader instead.

It has to exist in the system classloader so I have included it in "system" for inclusion in run.jar
