Catch Exception even if it isn't thrown, for Kotlin

[ejona86]

Kotlin does not observe checked exceptions. https://kotlinlang.org/docs/reference/exceptions.html#checked-exceptions . It sounds like that that means that even things like Runnable can throw checked exceptions.

Lots of code will be broken in such an environment, including lots of Guava. But for improved Kotlin handling we could consider making sure to handle Exception catching places we have RuntimeException catching if the application may have been called.

It's probably a good idea to confirm the behavior and discuss this problem with Guava folks and come to a unified agreement.

I'm interested in the result of this discussion.

We use grpc with Kotlin in production and although we have error handling explicitly enforced for our ServiceImpls, we do want to make sure our interceptors follow any convention we expect to be implemented.

One case is our server tracing instrumentation with datadog, which will need to be updated so that it correctly reports errors. eg. TracingServerInterceptor

Looks like fixed in this commit 1a42c8a
