Hey Hadrian, I started investigating the camel-bam code and one from statements I wrote is not true. The Process name can be set by calling the ProcessBuilder constructor. The Process-N name is a default behaviour.
Also, if it makes a sense to support delaying the activity? Eg making an activity suspended? I don't see use of it in my case so far, but that's might be required by other processes.
