> When external messages are routed to a waiting BPEL (BPE) process instance a
> ThreadLocal is initialised with a reference to the BPEEndpoint that is being
> routed to. Once the BPE event director returns at the completion of the
> business process this ThreadLocal is set to null. Normally this doesn't pose
> a problem, but in the case where the last statement before the reply (if the
> process doesn't have a reply the problem does not appear) is an InOnly MEP
> the business process returns immediately and by the time the InOnly invoke
> has filtered out to the integration layer the ThreadLocal variable has been
> set to null creating a race condition.
> The workaround is not to have an InOnly as the last statement in the business
> process that declares a receive/reply pair. This is not optimal but may be
> the best we can do until the new jbi deployment/integration using the new
> merged ODE is fully stable. I will start testing the merged trunk over the
> next week or so to gauge what the best direction to proceed with is.
