HttpServerResponse.send(publisher).then() does not propagate error signals

[rstoyanchev]

Expected behavior

When writing with HttpServerResponse.send(publisher).then(), if the writing Publisher completes with an error, the error should be observed from the subscriber side.

Actual behavior

The subscriber receives onComplete instead of onError.

Steps to reproduce

I observed this while experimenting with the sample for this issue. The writing to the response is in the ReactorServerHttpResponse. Only onComplete flows out of that.

Reactor Netty version

0.7.2

JVM version (e.g. java -version)

1.8

OS version (e.g. uname -a)

Linux/Ubuntu

Could we prioritize this issue to be addressed soon, i.e. leaving time before 0.7.3? The actual scenario I'm interested in testing, based on SPR-16051, is the effect of propagating a write publisher error after the response has been committed, but the issue here gets in the way.
