Description

This test passes in Groovy 2.5.6 - but not in 2.5.7/8:

https://github.com/grails/grails-core/blob/beafdce14d05f15abb18a079f9bb681f8761fe45/grails-plugin-rest/src/test/groovy/org/grails/plugins/web/rest/render/VndErrorRenderingSpec.groovy#L74-L109

Code where the error happens:

https://github.com/grails/grails-core/blob/7ab9e47ad805fbeb9433a488dd33f91bef44c0fa/grails-plugin-rest/src/main/groovy/grails/rest/render/errors/VndErrorJsonRenderer.groovy#L56-L75

The JSON produced includes an extra comma:

 ,"_links":{(,)"resource":{(,)"href":"http://localhost/books/1"}}},{"logref":"book.title.bad.1","message":"Title Bad","path":"http://localhost/books/1","_links":{(,)"resource":{(,)"href":"ht ,"_links":{(-)"resource":{(-)"href":"http://localhost/books/1"}}},{"logref":"book.title.bad.1","message":"Title Bad","path":"http://localhost/books/1","_links":{(-)"resource":{(-)"href":"ht
