public class JBossRMIClassLoader

extends java.rmi.server.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.

Another redeployment problem is that the getClassAnnotation(String) will end up using the old deployment class loader and this can result in NPEs do the class loader being destroyed. 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
