Hi,

I've downloaded jbpm-5.1.0.Final-installer-full.zip, and created a simple BPMN with two human tasks, the first is assigned to the user 'admin', the second is assigned to 'mary'.

When I try to start this process, it results in this exception: http://pastebin.com/Ww68Bqvz

If I change the process and assign the first task to 'Administrator', the issue is the same, however if I set 'krisv' as ActorId, then the process starts just fine.

For demonstration purposes it would be nice if the the 'admin' user could be set as ActorId as well – or in case you don't want to have this default, it would be great to have it documented how to enable that.

Here are the BPMN and minimal JAR containging the template files:

Thanks.
