Sean Ahn commented on ODE-262:
------------------------------
I'm not sure if we want to support unique="false" at all if we're going to
invest to this issue.
In reality, if we end up with more than one instance with the same correlation
key values and if what instance receives any successive non-instance creating
messages is non-deterministic, the outcome of processing of such messages
becomes non-deterministic. Therefore, supporting non-uniqueness does not do
anything.
> Duplicated correlation set values is accepted and creates a second instance
> instead of throwing an exception

> Key: ODE-262
> URL: https://issues.apache.org/jira/browse/ODE-262
> Project: ODE
> Issue Type: Bug
> Components: BPEL Runtime
> Affects Versions: 1.1.1
> Environment: Apache ODE 1.1.1 or 1.2
> Tomcat
> The counter example of infoq.
> Reporter: Amin Anjomshoaa
> Assignee: Karthick Sankarachary
> Fix For: 2.0
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The classical counter example of infoq
> (http://www.infoq.com/articles/paul-brown-ode) can be used. Sending the
> "init" message for the second (third, fourth, ... ) time with the value "foo"
> will create a new instance. I was expecting a CorrelationViolation exception
> when the second init message is arriving.
> All upcoming messages are then correlated with the last instance only.
