hi Strong i am new here and i want to contribute to hibernate project so i start with simple bugs, so that i can understand the structure and coding conventions of hibernate i start with these 2 bugs 1- DB2 HQL insert statement (https://hibernate.onjira.com/browse/HHH-7558) the problem here is that during the Session Factory initialization the sqlFunctions register Long data type as (big_integer ),while DB2Dialect class register it as (bigint) so when hibernate trying to find the data type of (bigint) in SqlFunctions (big_integer) hibernate throw null Pinter Exception , I change bigint to big_integer in DB2Dialect class and it works now 2- getForUpdateString() of HSQLDialect returns empty string (https://hibernate.onjira.com/browse/HHH-7479) The problem here is that HQL Data base didn't support (select for update) statement in hql version 1.8 but it support it now (from version 2.0) so i modify getForUpdate()@HSQLDialect class and it works now how can i commit my modifications (i already create my fork at git hub) thank you
