                 URL: http://jira.jboss.com/jira/browse/JGRP-261
             Project: JGroups
          Issue Type: Bug
    Affects Versions: 2.3 SP1
         Environment: Windows XP, Sun

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:
--not significant part skipped
JGroupsSendingModeTest$ServerASkeleton.getConnectionPoint192.168.33.113:1914
JGroupsSendingModeTest$ServerBSkeleton.getConnectionPoint111.111.111.111:5000
rspList = [sender=192.168.33.113:1926, retval=111.111.111.111:5000, received=true, suspected=false]
[sender=192.168.33.113:1914, retval=192.168.33.113:1914, received=true, suspected=false]

ipAdressesList = [111.111.111.111:5000, 192.168.33.113:1914]
--not significant part skipped

The output of the example for  the version 2.3 SP1 is the following one:
--not significant part skipped

JGroupsSendingModeTest$ServerASkeleton.getConnectionPoint192.168.33.113:1956
JGroupsSendingModeTest$ServerBSkeleton.getConnectionPoint111.111.111.111:5000
rspList = [sender=192.168.33.113:1959, retval=null, received=true, suspected=false]
[sender=192.168.33.113:1956, retval=null, received=true, suspected=false]

ipAdressesList = []

The investigation of the logs has shown, that in log for the version 2.3 SP1 the following message is being present :

            }
            catch(Exception e) {
                if(log.isErrorEnabled()) log.error("exception=" + e);
            }
        }
