(BPMN) In Latest source jbpm uses the name instead of the id for processes

In Latest source jbpm uses the name instead of the id for processes...
In my opinion this is the wrong behaviour as the name of a process will be converted to a id.
So if you want to start a process via: executionService.startProcessInstanceByKey("process4711") it will throw a exception.

Example Process for this:
<process id="process4711" name="Could be a very long description and is not used to IDENTIFY">
