Hi,
no it's not a bug, it's a feature (checked exception)

as you said: <code>value = null</code>

<code>
if (value instanceof String) {
          List<String> candiates = extractCandidates((String) value);
          task.addCandidateUsers(candiates);
        } else if (value instanceof Collection) {
          task.addCandidateUsers((Collection) value);
        } else {
          throw new ActivitiException("Expression did not resolve to a string or collection of strings");
        }
</code>
