Would be this:

Imagem inline 2
i noticed 2 thing doing this test, 1st, the ID binded on workorder/engineer can be the same, for example, it will run if I have an workorder id 0 and an engineer id 0, and that it will run if provided time enough to do the comparison by the xml file, otherwise, it will present a result full of "null's".

I generate the workorder/engineer this way:
--------
List<Engineer> engineerList = new ArrayList<Engineer>();
for (int i = 1; i < 1001; i++){
engineerList.add(new Engineer(i, "engineer " + i, 8 ));
}

List<WorkOrder> workOrderList = new ArrayList<WorkOrder>();
for (int i = 1002; i < 3002; i++){
workOrderList.add(new WorkOrder(i, (new Random().nextInt(5-1+1)+1)));
}
----------------

in order to stop receiving nulls, i increased the termination from 5s to 120s, and it worked

----------------
<termination>
    <maximumSecondsSpend>120</maximumSecondsSpend>
</termination>
----------------

Now try 2000 workorders and 1000 engineers and see what it does ;-)

Just to knowledge, i'm sending the graph of memory usage when running it with, first marker(between first 2 green lines) peak with 10 workorders and 5 engineers, and, secong marker (between last 2 green lines),  26 workordes and 10 engineers.

I wonder why it worked on the 5.5.0.Final with the cloudbalance but not with my workorder example that was much simpler,
Me too. All the examples / unit tests work with 5.5.0.Final, but there's clearly a case they don't cover.
Good thing is that 5.6 will be out soon.

It worked with the 5.5.1-SNAPSHOT

I wonder why it worked on the 5.5.0.Final with the cloudbalance but not with my workorder example that was much simpler, i mean, the rule was only a hard constraint and the pojo simples though.

Okay I'll try it now and then  post the result.
