Description Dmytro Pishchukhin CLA 2010-08-05 11:26:58 EDT 
Build Identifier: 7.2.0-SNAPSHOT

it seems that in code

for (EventListener l : listeners)
                    {
                            if (l.getClass().getName().equals(className))
                                return;
                    }

l variable is null at some case
