NPE in HttpResponseSnippet when documenting a response with a custom HTTP status

[flo076]

Hello,

In my mind, the issue #639 does not seem to be finished.

We have an exception, with spring-restdocs.version in version 2.0.4.RELEASE, when try to generate documentation for an endpoint that returns

return ResponseEntity.status(215).body(elements)

The exception :

java.lang.NullPointerException
	at org.springframework.restdocs.http.HttpResponseSnippet.createModel(HttpResponseSnippet.java:62)
	at org.springframework.restdocs.snippet.TemplatedSnippet.document(TemplatedSnippet.java:78)
	at org.springframework.restdocs.generate.RestDocumentationGenerator.handle(RestDocumentationGenerator.java:191)
	at org.springframework.restdocs.mockmvc.RestDocumentationResultHandler.handle(RestDocumentationResultHandler.java:52)

	at org.springframework.test.web.servlet.MockMvc.perform(MockMvc.java:190)

Closing in favour of #653.
