When you have entities defined for tables that can not be found (do not exist in the DB schema).

This can occur when you define a set of entities and want to use them across a number of DB schemas and not all the entities have a matching table in all the schemas.

Ebean should detect which entities do not have a matching DB table ... and just log a warning (and should not barf fatally).

This bug occurs when there are manual @JoinColumn type annotations on the entity bean... and in this case Ebean barfs rather than just logging the warning.

Find an Entity that has a manual table join on it ... change the base table to something that does not exist in the current DB schema

@Entity
@Table(name="no_such_table")
public class Comment {

...
@ManyToOne
@JoinColumn(name = "link_id")
CommentLink link;

Fixed in version 1.0.3
