[jboss-jira] [JBoss JIRA] Updated: (JGRP-261) The value returned by the server method is not delivered by RpcDispatcher to client

[Bela Ban (JIRA)]

     [ http://jira.jboss.com/jira/browse/JGRP-261?page=all ]

Bela Ban updated JGRP-261:
--------------------------

    Fix Version/s: 2.4

Fixed. Problem was that IpAddress as return value is Streamable, so it was marshalled using IpAddress.writeTo(). However, Message.getObject() still used ObjectInputStream.readObject(), so that failed.

> This bug was revealed by the unit testing, when trying to update to the version 2.3 SP1 from 2.2.9.1
> The call to the PpcDispatcher in the version 2.2.9.1 works properly.
> When performing the test example, it can be seen, that in version 2.3 SP1 the methods are being called on the server, but the results of the call are not delivered to the client.
> The output of the test example for the version 2.2.9.1 is the following:
