The id length is limited to 64 characters (#ACT-115). In the BpmnDeployer activiti generates a processDefinitionId with the following semantic:
When using with a UUID based IdGenerator the limit of 64 characters is reached and the processDefinitionId is not in the aggregated colon-form (which is expected by the CamelBehavior):
So an exception is thrown.
I suggest the following workaround until #ACT-1642 is resolved.
