Memory issue using BO XI Enterprise SDK and ISecurityInfo

Question

Hello everybody
I have a big issue using the XIR2 SDK when I want to get rights for an object (universe or overload for example). When I start my process the memory used keep growing, starting for 20 mb to more than 100mb and if I have too many objects, the script hangs. I tried to simplify my code to make it understandable :
My Main Class
               Vector<Integer> vIntOv = OverloadsFactory.getAllOverloadsID();
               Iterator<Integer> itOvIterator = vIntOv.iterator();
               Integer cIdOv = null;
               while(itOvIterator.hasNext()) {
                    cIdOv = itOvIterator.next();
                    System.out.println("ID OV = "+cIdOv);
                    Overload ov = OverloadsFactory.getOverloadById(cIdOv);
                    Iterator<PrincipalRestricted> itRestPrin = ov.getPrincipalRestricted().iterator();
                    PrincipalRestricted cPrin = null;
                    while(itRestPrin.hasNext()) {
                         cPrin = itRestPrin.next();
                         System.out.println("     REST = "+cPrin.getPrincipalName());
                         cPrin = null;
The getOverloadById method in OverloadFactory class :
     public static Overload getOverloadById(int overloadID) throws OverloadException, IOException, ClassNotFoundException, SDKException {
          String name="";
          String creationTime="";
          Vector<RowRestriction> vRestrictedRows = new Vector<RowRestriction>();
          Vector<ObjectRestriction> vRestrictedObjects = new Vector<ObjectRestriction>();
          Vector<PrincipalRestricted> vPrincipalRestricted= new Vector<PrincipalRestricted>();
          String boQuery="SELECT * " +
                    "FROM CI_APPOBJECTS " +
                    "WHERE SI_KIND='OVERLOAD' AND SI_ID="+overloadID;
          Iterator<IOverload> itOverload = BoxiRepositoryManager.getInstance().executeQuery(boQuery).iterator();
          if(itOverload.hasNext()) {
               IOverload currentIOverload = itOverload.next();
               name=currentIOverload.properties().get("SI_NAME").toString();
               creationTime=currentIOverload.properties().get("SI_CREATION_TIME").toString();
               //System.out.println("OVERLOAD : "+currentIOverload.getTitle()+" / UNIVERSE : "+UniversesFactory.getUniverseById(currentIOverload.getUniverse()).getName());
               Iterator<IRowOverload> itRestrictedRows=currentIOverload.getRestrictedRows().iterator();
               while(itRestrictedRows.hasNext()) {
                    IRowOverload currentRestrictedRow = itRestrictedRows.next();
                    //System.out.println("     RR ("+currentIOverload.getID()+") Where Clause : "+currentRestrictedRow.getWhereClause());
                    vRestrictedRows.add(new RowRestriction(currentRestrictedRow.getRestrictedTableName(), currentRestrictedRow.getWhereClause()));
               //System.out.println("     RR ("+currentIOverload.getID()+") Size : "+vRestrictedRows.size());
               Iterator<IObjectOverload> itRetsrictedObjects=currentIOverload.getRestrictedObjects().iterator();
               while(itRetsrictedObjects.hasNext()) {
                    IObjectOverload currentRestrictedObj = itRetsrictedObjects.next();
                    //System.out.println("     RO ("+currentIOverload.getID()+") Object Name : "+currentRestrictedObj.getObjectName());
                    vRestrictedObjects.add(new ObjectRestriction(currentRestrictedObj.getObjectID(), currentRestrictedObj.getObjectName()));
               Iterator<IObjectPrincipal> itIObjectPrincipal = currentIOverload.getSecurityInfo().getObjectPrincipals().iterator();
               while (itIObjectPrincipal.hasNext()) {
                    IObjectPrincipal currentIObjPrincipal = itIObjectPrincipal.next();
                    vPrincipalRestricted.add(new PrincipalRestricted(currentIObjPrincipal.getID(),currentIObjPrincipal.getName()));
               itOverload = null;
               return new Overload(overloadID,currentIOverload.getUniverse(),name, vRestrictedObjects, vRestrictedRows, vPrincipalRestricted, creationTime);
          } else {
               throw new OverloadException("This Overload ID is not valid");
At the beginning I thought it was a problem in my own code but if you comment the following part in the above method, you'll see that the memory increase will not happen anymore :
Iterator<IObjectPrincipal> itIObjectPrincipal = currentIOverload.getSecurityInfo().getObjectPrincipals().iterator();
               while (itIObjectPrincipal.hasNext()) {
                    IObjectPrincipal currentIObjPrincipal = itIObjectPrincipal.next();
                    vPrincipalRestricted.add(new PrincipalRestricted(currentIObjPrincipal.getID(),currentIObjPrincipal.getName()));
Here the error
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

So it why I think that either there is an issue with "getSecurityInfo()" or I'm using it in a bad way. I tried many things like nulling my objects (even if in java the garbage collector does that by itself), changing my code... but no improvements, it's why I m requesting help from the experts
Thanks to you
PS : sorry for my grammar, i'm french
PS 2 : i just want notify that I'm not a java expert so if you have to criticize my code, no prob

Hi Merry
Thanks a lot for answering me. I didn't know that "getObjectPrincipal" takes so much memory for running.
According to you is it normal that the used memory keep growing even after nulling my objects ? For me after requesting the Principales for an object (overload or universe) the memory used should be released. It seems that even after the process an object created in the ISecurityInfo class is still living...
Thanks again for taking time to help me
