Description Tomasz Slota 2006-08-18 14:42:39 UTC 
We should detect following situations that cause deployment error:

-- 1
@Entity class A{
   @ManyToMany(mappedBy="as") List<B> bs;
}

@Entity class B{
   @ManyToMany(mappedBy="bs") List<A> as;
}

-- 2
@Entity class A{
   @ManyToMany List<B> bs;
}

@Entity class B{
   @ManyToMany List<A> as;
}

'mappedBy' should be used exactly once. The same applies for OneToOne annotation.

See issue 82571 for additional info.

Corresponding hints should allow adding or removing the 'mappedBy' attribute, depending on 
situation.
