I have a big problem that don't let me continue testing my process.

My pb seams to be simple, but .... I have found no solution 

So... in few words; I have a method executed concurrently by two or more threads. This method set a processInstance variable; and this variable is recuperated by a second thread to be updated. The var is java List that I recuperate to add a new element. 

The pb is, when the second process gets the var setted by the first one, the variable is always null.... 

So I added a logger to inspect the var just after setting it, and it is always null. But the process is using it internally and it works with no problems :(

List<PtlReportedInfo> confirmedMsgs= (List<PtlReportedInfo> ) jbpmManager.getVariable(bpmId, PtlProcessVariables.CONFIRMATION_MSGS);
  |         log.log(Level.INFO, "________________confirmedMsgs_________________"+ confirmedMsgs);
  |         List<PtlReportedInfo> initialVar= confirmedMsgs;
  |         if(confirmedMsgs==null){
  |           confirmedMsgs=new ArrayList<PtlReportedInfo>();
  |         }
  |         confirmedMsgs.add(ptlInfo);
  |         jbpmManager.setProcessVariable(bpmId, PtlProcessVariables.CONFIRMED_MSG,
  |             confirmedMsgs);
  |         log.log(Level.INFO, "--"+ jbpmManager.getVariable(bpmId, PtlProcessVariables.CONFIRMATION_MSGS));

I need an urgent help please :( 
I have no more ideas
