[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-672) Missing @Entity silently fails

Hontvári József commented on ANN-672:
-------------------------------------

Not annotation specific, but related: while a HQL query fails runtime because of the unknown entity, a Criteria query doesn't. It simply returns an empty list. It can be argued that this is the correct behaviour ("I tried all day, still I wasn't able to find a single java.awt.SystemTray in that database"), but at least it would worth a more honest warning message too ("I couldn't eve try to find it, because I have no idea how a java.awt.SystemTray can be placed into a database").

> Hibernate config.xml contains a class in a <mapping class=... element. The class has no @Entity annotation by mistake. There is no exception thrown and I haven't find any log entry even on trace level, other then the usual
> o.h.c.AnnotationConfiguration null<-org.dom4j.tree.DefaultAttribute at 1f4cf6f [Attribute: name class value "...
> which appears for all (valid) classes too. The problem is manifested only runtime, when Hibernate complains that the entity is undefined.
