wondering if we should rather catch IOException and rethrow UncheckedIOException. getting tired of all these checked exceptions, which force us to move to CheckedFunction.

Well, I'm on the fence on this. We already use CheckedFunction for response parsers I think we could also use CheckedFunction for request converters? I don't feel like it adds a lot of boling code.

I think that the assumption up until now was that these methods wouldn't throw exceptions. if they do, we have to modify the async methods to catch and call the listener. I think users wouldn't expect to have exceptions thrown with async methods, even if this happens synchronously before the request gets sent :)

I think I did it in performRequestAsync() ?

oh I had missed this. But we only catch IOException, while we can also throw IllegalStateException now?

Right - it should catch Exception instead (and also ensure that the listener get called anyway because I just notive that performRequestAsync throws an IllegalArgumentException too.

oh oh, I think those exceptions thrown in RestClient#performRequestAsync are a problem to be handled in the low level client. the bug is there I'm afraid.

oh right - I didn't notice I was looking at the RestClient itself. I'll take care of changing it
