MarshallingView should avoid temporary byte array when copying to response [SPR-11646]

[spring-projects-issues]

Juergen Hoeller opened SPR-11646 and commented

MarshallingView's current code:

StreamUtils.copy(baos.toByteArray(), response.getOutputStream());

can be optimized to:

baos.writeTo(response.getOutputStream());

in order to avoid the temporary copy in a byte array.
