> 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.
