2021 Week 40-42 (from Oct 4)
Due to the fix for JBPM-9623, the ProcessInstance is no longer retrieved in readOnly mode when process variables are fetched. This can easily lead to an OptimisticLockException:

As this call does not update any entities, it should fetch the ProcessInstance in readOnly mode to avoid the update to the SessionInfo object.
