--------------------------------------
Will something be done about this?
It keeps occuring at the most inconvenient times, mostly when my boss is breathing down my neck.

> Project: JBoss Application Server
> Issue Type: Feature Request
> Security Level: Public(Everyone can see)
> Components: System service
> Affects Versions: JBossAS-4.0.3 SP1, JBossAS-4.0.4.CR2
> Environment: jboss-4.0.3SP1 and jboss-4.0.4CR2 on Windows 2000 server using JVM 1.5.04
> WAR file is built on JDK 1.5.04 using the ANT 1.6.5 WAR task

> To avoid unpredictable "org.jboss.deployment.DeploymentException: Unexpected end of ZLIB input stream" exceptions could a grace period (delay) be added to the JBoss deployment deployer. This delay should be applied as follows:
> 1. Scanner finds new deployments
> 2. WAIT for grace period
> 3. Scanner deploys new deployments
> Setting the grace-period to 0 would emulate the current JBoss behaviour

[JBoss JIRA] Commented: (JBPM-165) process instance versioning
by Bernd Ruecker (JIRA)
[ http://jira.jboss.com/jira/browse/JBPM-165?page=comments#action_12354677 ]
Bernd Ruecker commented on JBPM-165:
------------------------------------
What I have already as a command (not yet committed, because the test is not ready) is to change the version of a process instance. But I just changed the associations from the runtime objects to the new version defintion objects (this code we had already in out toolkit for jbpm).
But this is not yet the solution Tom wanted to have. But I can commit it today as a "preview", so everybody can have a look at it.

> i think jbpm could offer some degree of assistence in process instance versioning.
> when a new version of a process is deployed, jbpm could do the following conversion for a process instance :
> * input required: mapping of the nodes from the old to the new definition.
> * cancel the old process instance
> * create a new process instance and copy the runtime (exe) information such as tokens and process variables from the old process instance.
> * then establish a special link between the 2 process instances to indicate that the new process instance is the continuation of the old process instance.
> this way we can avoid the problematic conversion of logs, while still keeping them in the system.
