+ // checks first to see if there's any handlers already set
+ // and if not it creates them. If this method executes prior

+ // 1) there's no handlers installed so there's none to

setUseParentHanders(false)

+ // Therefore we need to force the class to be loaded.
+ // This should really be resolved by Parquet.
