> Currently, when an RPC ask() call fails, we get a rather unhelpful exception with a stack trace from akka's internal scheduler.
> Instead, we should capture the call stack during the invocation and use it to give a helpful error message when the RPC call failed. This is especially helpful in cases where the future (and future handlers) are passed for later asynchronous result handling (which is the common case in most components (JM / TM / RM).
> The options should have a flag to turn it off, because when having a lot of concurrent ask calls (hundreds of thousands, during large deploy phases), it may be possible that the captured call.
