> Two things:
>  * We truncate RpcServer output to 1000 characters for trace logging. Would be better if that value was configurable.
>  * There is the chance for an ArrayIndexOutOfBounds when truncating the TRACE log message.
> Esteban mentioned this to me earlier, so I'm crediting him as the reporter.
