> The following query fails silently to return a correct result select v1.username, v2.username from user_ety v1, user_ety v2 where v1.username = '1' and v2.username = '2'. It returns one row with "1,1" instead of one row with "1,2".
> The query works with pre JPA CMP EJBs (ver 2.1) but fails when moved to JPA based persistence.
> This failure is very dangerous since it is silent and without manually checking data it is impossible to determine if a correct set is returned.
> The workaround is to use aliases and modify the query so it looks like that:
> select v1.username as username1, v2.username as username2 from user_ety v1, user_ety v2 where v1.username = '1' and v2.username = '2'.
