Accessing errors in Swagger read

[Yosef]

Hello, 

I'm using jaxrs Reader to build documentation as part of swagger-akka-http. I've noticed all errors in the reader are swallowed and logged. Is there a way to test / verify that the swagger has been read and generated correctly? 

For example, that I didn't accidentally put a wrong reference in `dataType` annotation that would result in a `ClassNotFoundException` during reading that gets swallowed?

Many thanks!

Y
