Querying BOE security - getObjectPrincipals() has memory leak?

Question

Hi,
I am querying the BOBJ Enterprise security and noticed that when I introduce the getObjectPrincipals() method in my code, my program consumes a great deal of additional memory, and will eventually fail due to insufficient heap space as the code iterates through the reports.  The issue does seem to be tied to specifically this method, as the memory is handled fine with everything else the same.  Is there a known memory leak with this method?  I am currently testing against XI R2 SP2 and noticed in release notes for SP5 there was a documented memory leak with a similiar method in the COM SDK - getAnyPrincipals(). 
Can anyone shed any light on this?  I can provide code samples too if need be...
Thanks!

Thanks for the responses guys. 
Ruben - I did try to use remove() for both of my iterators in use (the first of which contains all principals who have rights for the given InfoObject, and the 2nd contains all of the explicit security rights for the principal) - this unfortunately didn't have any affect on the memory usage.  What I tried was as follows:
ISecurityInfo objSecurityInfo = boInfoObject.getSecurityInfo();
IObjectPrincipals objPrincipals = objSecurityInfo.getObjectPrincipals();  //THIS I BELIEVE TO HAVE MEMORY LEAK
Iterator objPrincipalIterator = objPrincipals.iterator();
//retrieve rights applied to object
while (objPrincipalIterator.hasNext())
        ...get security Role information for each principal
        //now get explicit rights information
        ISecurityRights objPrincipalExpRights = objPrincipal.getRights();
        Iterator objPrincipalExpRightsIterator = objPrincipalExpRights.iterator();
        while (objPrincipalExpRightsIterator.hasNext()
                   ..process explicit rights
                   objPrincipalExpRightsIterator.remove();
obPrincipalIterator.remove();
Ted,
I was already batching the # of InfoObjects to retrieve security information for, but just to be sure I greatly decreased this number and did not see any improvement in memory usage.  I actually worked a case with SAP on this question, and they confirmed there was a memory leak with the getObjectPrincipals() method.  They confirmed this was fixed for XI R2 in SP5 for the .Net and COM SDKs, but not for Java.  Is there anything else I can try?  Using getObjectPrincipals(1) for only explicit rights works great as far as memory consumption, but only exposes users with custom roles and I need to retrieve principals with any type of role.
Thanks!
