I agree that my original use of the assignment handler for the start-task etc. was flawed - hence why I've now removed it.

Most often it is a classloader issue if you see this different behaviourIt was in my first post, but probably not obvious. Yes, it does seem to be a classloader issue - running in the context of JUnit - for now I'm getting:
java.lang.ClassCastException: org.springmodules.workflow.jbpm31.JbpmHandlerProxy
  |     at org.jbpm.graph.def.Action.execute(Action.java:121)
Following from:
getJbpmTemplate().execute(new JbpmCallback() {
  |             public Object doInJbpm(final JbpmContext context) {
  |                 // Create a new process instance
  |                 final ProcessInstance pi = context.newProcessInstanceForUpdate(processName);
  |                 if (pi != null) {
  |                     pi.getRootToken().signal();
  |                 }
  |                 return null;
  |             }
  |         });

As I've got a deadline looming, I have no choice but to give up on trying to solve this conundrum, for now.

Thanks for your input so far. If anyone has any similar experience trying to JUnit test their Spring app (with jBPM 'under the hood') then I'd be glad to hear how you got around this issue.
