> Attached is a simple test case that
> 1) Deploys process definition with two nodes
> 2) Starts 20 executor threads
> 2) Starts the process instance that will asynchronously execute action on the second node
> 4) The second node writes a record to the database
> The test case needs to be executed multiple times to see the incorrect behaviour.
> This is an example of run output
