update on an entity with a javax.validation.constraints.NotNull constraint on a ManyToMany relation causes an AssertionFailure if the relatated entity also contains a ManyToMany relation to a third entity and all relations have the fetchtype lazy. 

Here is the given entity structure:
@Entity class A {
   String textA;

   @NotNull
   @ManyToMany
   Set<B> b;
}
@Entity class B {
   String textB;

   @NotNull
   @ManyToMany
   Set<C> b;
}
@Entity class A {
   String textC;
}

this pseudocode causes the error:
startTransaction
A myA = find(A.class,1);
myA.setText("newText");
commit

See the attached testcase for more details
