    Description

      When a server implementation throws an exception handling an RPC, the Handler thread catches it and logs it before responding with the exception over the IPC channel. This is currently done at INFO level.

      I'd like to propose that, if the exception is an unchecked exception, it should be logged at WARN level instead. This can help alert operators when they might be hitting some kind of bug.
