Some uncaught exceptions just show generic `RuntimeException` instead of the root cause

[edenman]

I'm migrating to Bugsnag and I'm a bit disappointed by the detail raised in this issue.

In case you can't see that link:

What's weird is that other issues display the root cause just fine. Is there a setting that I can use to control which exception is displayed at the top level?

The full stacktrace of the first issue:

Thanks for the report, @edenman. There is a lot of options here. Potentially we could mark reflection exception frames as not likely being the root cause, which would then surface the NPE in this particular case. 🤔 Might have to think about this one more to determine the general case.

[JakeWharton]

InvocationTargetException always wraps another exception (potentially recursively, as evidenced by the included trace) as a result of reflective invocation, so not including it as a potential cause would be a welcome improvement.

That makes sense to me. Thanks, @JakeWharton.

Update for visibility: The change is something we should make during event processing, rather than have the client process and discard exceptions or stack frames. Investigating how we should detect and better surface the underlying exception.
