@djelinski I fixed the issue with stack traces being printed for expected exceptions. If you could have a look again?
Those exceptions stacks were in fact printed twice: once in the handler and once in the HttpServerAdapters infrastructure. Fortunately the latter can be switched off by adding an "X-expect-exception:" header, and the former have now been supressed.
