Pedro - we ended up doing the following. I feel like there definitely a better way as Mauricio suggested:

1. Find active nodes
2. Find all nodes after nodes in #1
3. Find all human nodes in #2


Notes on 1.:
ProcessInstanceLog processInstanceLog = jpaDbLog.findProcessInstance(new Long(instanceId))

Notes on 3.:
|  |  |  |  |  | while (node != null) { |
|  |  |  |  |  |  | if (node instanceof HumanTaskNode) { |
|  |  |  |  |  |  |  | list.add((HumanTaskNode)node); |
|  |  |  |  |  |  | } |
|  |  |  |  |  |  | connections = null; |
|  |  |  |  |  |  | connections = node.getOutgoingConnections("DROOLS_DEFAULT"); |
|  |  |  |  |  |  | if (connections != null && connections.size() > 0) { |
|  |  |  |  |  |  |  | node = node.getOutgoingConnections("DROOLS_DEFAULT").get(0).getTo(); |
|  |  |  |  |  |  | } else { |
|  |  |  |  |  |  |  | break; |
|  |  |  |  |  |  | } |
|  |  |  |  |  | } |


I hope this helps.
