Posting text/uri-list to the wrong location results in a 500 [DATAREST-818]

[spring-projects-issues]

Christian Bongiorno opened DATAREST-818 and commented

When submitting a text/uri-list to add to a collection of relationships (as per the link above),

a 4xx error is more appropriate.

This error was my fault, definitely. But the 500 error set me scratching my head for a while. It was totally a client side problem

Hi, I'd like to work on this. The 500 occurs because UriListHttpMessageConverter matches text/uri-list requests but returns a CollectionModel instead of the target domain type. When PersistentEntityResourceHandlerMethodArgumentResolver tries to bind that to the entity, it fails downstream. I'll add a type check after reading the body to throw HttpMessageNotReadableException (mapped to 400) instead. PR coming shortly.
