This is based on my understanding that a process definition is an immutable entity, which
is defined in XML.
The state of running processes is persisted in the database. For many a reason It cannot
be expected that jBPM can be updated for running proccess. If this feature is required we
need to see this reflected in the test suite. In other words, as long as there are no
automated tests that verify that an update of jBPM from version X to version Y for a non
trivial set of running processes - this feature is not there.
The API will support
| ProcessEngine.prepareForShutdown()
|
This will allow processes to terminate, while others cannot start. A user is expected to
setup a new instance of jBPM version Y that can receive new process requests.
From that perspective, it is unnecessary and not even desired to
provide backwards compatibility for database layout.
