[undertow-dev] exchange.getResponseSender().send issues

[Hicks, Matt]

Well, I just added an IoCallback and now I'm getting an error: Attempted to
write 144780 bytes however content-length has been set to 144772

This, I think, raises both a question and an issue:

Question: Should I not be setting the Content-Length myself even when using
exchange.getResponseSender().send?
Issue: Seems like a bug that without an IoCallback the error is just
absorbed and never logged anywhere.
