Gail Badner commented on ANN-824:
---------------------------------

I problem with the missing join table is because associations are mismapped. I've opened ANN-841 for that issue.

> MSSQL, DB2, and Sybase require primary key columns to be non-nullable. Some unit tests are failing using those DBs  because a primary keys are defined with one or more nullable columns. This is happening with both trunk and v3_3_1_GA_CP.
> I see other JIRA issues that sound related that are marked as fixed, so I'm surprised to see these failing in trunk. 
> HHH-1935 sounds related. It mentions a bug in SchemaUpdate using @MapKey with @CollectionOfElements.
> Workarounds are:
> - add "nullable=false" to @JoinColumn
> - add "optional=false" to @ManyToOne
> - add an @AttributeOverride with @Column(name="mapkey", nullable=false) in case of a @CollectionOfElements using a Map
> - add "nullable=false" in @Column when inside a @CollectionId or inside @MapKey
> I've included the table DDL causing the failure. Also, there were some tests I couldn't get to pass using a workaround.
