Bela Ban updated JGRP-2263:
---------------------------
Steps to Reproduce:
{code:java}
public class SimpleChat {
JChannel channel;
RpcDispatcher dispatcher;
private static final RequestOptions IMPORTANT = new
RequestOptions(ResponseMode.GET_ALL,
TimeUnit.SECONDS.toMillis(60)).setFlags(Message.Flag.DONT_BUNDLE);
private void start() throws Exception {
channel = new JChannel();
dispatcher = new RpcDispatcher(channel, new Test() {
});
channel.connect("ChatCluster");
channel.getState(null, 10000);
Method test = Test.class.getMethod("test");
Object o = dispatcher.callRemoteMethods(null, new MethodCall(test), IMPORTANT);
System.out.println(o);
channel.close();
}
public static void main(String[] args) throws Exception {
new SimpleChat().start();
}
public static class Test {
public Object test() {
return new EError(EError.EErrorKind.WRONG_PARAMS);
}
}
public static class EError extends Error {
private static final long serialVersionUID = 1L;
enum EErrorKind {
WRONG_PARAMS,
}
final EErrorKind code;
public EError(EError.EErrorKind code) {
this.code = code;
}
}
}
{code}
was:
{code:java}
public class SimpleChat {
JChannel channel;

channel.getState(null, 10000);
Method test = Test.class.getMethod("test");
Object o = dispatcher.callRemoteMethods(null, new MethodCall(test), IMPORTANT);
