Description

The Jersey ErrorMessagesException supports a list of messages, and is how jersey itself builds up errors.

{{GenericExceptionHandler }} doesn't have special handling here and converts to a 500, discarding all the text as it does so.

the handler should recognise the exception, log the messages and build up the response text from it.
