ktor 1.0 alpha-1,2,3: StatusPages exception handling misbehaves when exception thrown inside coroutine

[marshallpierce]

In short, exception<FooException> {} seems to behave differently when an exception is thrown immediately inside a route's handler lambda vs when it's thrown inside, say, an async coroutine builder in that lambda.

Minimal reproduction: https://bitbucket.org/marshallpierce/ktor-exception-handler-repro/src/master/

happens with -beta-1 too.

Had no change to fix it in beta, sorry.

[marshallpierce]

No problem; just keeping the issue up to date so you don't have to bother checking if it's fixed in later versions :)

Fix is available in 1.0.0-beta-2
