com.hp.hpl.jena.query.ResultSet remove row

[Jorge Christodoulou]

Hi, the ResultSet man again :)Is it possible to remove a "row" from a 
com.hp.hpl.jena.query.ResultSet  during a for loop?
I tried:
for(; rSet.hasNext() ;){                        
if(listCSD.contains(rSet.nextSolution().get(commonVars.get(0)).toString()))     
                        rSet.remove();          }
but it throws this exception:java.lang.UnsupportedOperationException: 
ResultSetMem: Attempt to remove an element
