In 5.2. ConstraintViolation, the Bean Validation 1.1 spec states that:

isInIterable() returns true if the node represents an object contained in an Iterable or in a Map, false otherwise.

In the RI, isInIterable() also returns true for arrays - and the RI counts on it in various places.

We thought it was weird the TCK didn't have a test broken due to this but it's worse than that: the TCK has a test relying on isInIterable() being true for arrays.

See:

• https://github.com/beanvalidation/beanvalidation-tck/blob/master/tests/src/main/java/org/hibernate/beanvalidation/tck/tests/validation/PropertyPathTest.java#L1712

Our inclination would be to fix the spec as it seems like an error.
