>
> When I have some entities referencing each other (a cycle), the annotation @Valid is on the corresponding getters and there is not really something to be validated on these entities (no @NotNull, ... is present) I end up in a recursion which leads to a stack overflow. 
> If there are some @NotNull the detection of cycles does work fine.
