[hibernate-dev] SessionImpl.list(CriteriaImpl criteria) returns an empty list when no implementors exist

[Steve Ebersole]

We could perhaps log.warn like we do for HQL, but throwing an exception
is not a good idea imo.

> Hi all, in using hibernate v31final SessionImpl.list(CriteriaImpl criteria), I had an issue where hibernate would return an empty list when no implementors existed for the entity name(I had mistaken deleted the entity from the hibernation configuration file). The confusion arose in that this was be mistaken for a query that would return no rows. In looking at the code, it appears that the results list is always initialized to an empty list rather than null. Likewise, no exception is thrown if the entity does not exists, whereas when using HQL an org.hibernate.hql.ast.QuerySyntaxException exception would be thrown. Opinions on initializing the results list to null or throwing an exception if the implementators exist for the desired entity?
