No execution found for cancel boundary event

Description

I've been trying to get a really simple cancel boundary event example working on Activiti 6 (both beta 2 and the current snapshot), but it fails with an ActivitiException with the message "No execution found for sub process of boundary cancel event boundaryCancelEvent". This problem didn't occur in Activiti 5 and changing the cancel events to error events allows the process to complete. Is there something wrong with the bpmn file or is this a bug in the engine?
Thank you!
