NPE while reading props of POJO with orientdb #16

Closed hboumedane closed 9 years ago

hboumedane commented 9 years ago

I'm having a null pointer exception when trying to access property of a POJO :+1: here the code who's producing this exception : 

        List<Table> tables = _tableManager.getAllTables(); //this call findAll
        boolean founded = tables.parallelStream().allMatch(t -> t.getUuid().equals(uuid));

and here the exception :
