I solved this problem by defining a global boolean variable named "modifySolver" which be false by default. You can handle this problem as I show bellow:

else if (eventKind.equals (ENTRY_MODIFY))
        {
            if (event.count() == 2)
            {
                getListener(getDirPath(key)).onChange (FileChangeType.MODIFY, file.toString ());
            }
            /*capture first modify event*/
            else if ((event.count() == 1) && (!modifySolver))
            {
                getListener(getDirPath(key)).onChange (FileChangeType.MODIFY, file.toString ());
                modifySolver = true;
            }
            /*discard the second modify event*/
            else if ((event.count() == 1) && (modifySolver))
            {
                modifySolver = false;
            }
        }
