i get this warning:

process xml warning: warning: no swimlane or assignment specified for task '<task xmlns="urn:jbpm.org:jpdl-3.1" name="schedule" blocking="false" signalling="true" priority="normal"/>'

it seems a bit odd to generate a warning on a valid process definition.

i think it should either be illegal to have a task without an assignment or swimlane, or there shouldn't be any warning at all (maybe lower the logging level to INFO).
