[JBoss JIRA] Created: (JGRP-987) Make many classes immutable

Make many classes immutable
---------------------------
Key: JGRP-987
URL: https://jira.jboss.org/jira/browse/JGRP-987
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.x
Currently, a lot of classes could be immutable if it wasn't for the readFrom() method to initialize itself from an input stream.
However, if we had a factory, which reads and constructs immutable instances of classes, then we could turn a lot of classes into immutable classes, for example all headers should be immutable.
The code for marshalling and unmarshalling could be generated, e.g. based on an XML description of the data layout of a class.

shared_transport concurrency problem - starting several at the same time causes "timer cannot be retrieved from protocol stack"

Key: JGRP-964

Issue Type: Bug
Affects Versions: 2.7
Environment: Win2000, JVM = JRockit 6
Reporter: Edward Kuns
Assignee: Bela Ban
Attachments: CoordinationBus.xml
I have an application that starts four jgroups NotificationBus's that all share the same UDP transport (with singleton_name="...") but are otherwise distinct. Recently, the application started to fail to start with the following stack signature:
2009-04-27 13:56:50,425 -0500 ERROR [JGroupsTest] - Exception running bus

I created a test application that does nothing but start these four busses, and if I start them simultaneously, I can always reproduce the above error. I will attach the test application.

[JBoss JIRA] Created: (GPD-345) XML namespaces are not consistent between GPD and the engine

XML namespaces are not consistent between GPD and the engine
------------------------------------------------------------
Key: GPD-345

Project: JBoss jBPM GPD
Issue Type: Bug

The graphical designer and the process engine do not use the same XML namespace. GPD uses http://jbpm.org/4/jpdl whereas the engine uses http://jbpm.org/4.0/jpdl.
The consequence is that a process created with the designer does not work in the engine. You get errors like these:
