Hi Adam,

in java 11 was added HttpClient, which you use in this example (https://www.adam-bien.com/roller/abien/entry/sending_a_json_document_via). I am using this client very often, but still have a question, what is a proper way to consume json from the response? In HttpResponse.BodyHandlers we can chose from ofString(), ofFile(), ofInputStream() and few more, but we do not have any way to have just json. Even in jdk 17, we do not have this possibility. I found this Question and Answers (https://stackoverflow.com/q/57629401/865448) but it looks like kind of workaround.
So my question is: what is a nice a recommend by you way to do this (get response as json)?

Kind regards!

Hi, Adam!

If we look at the Response class(https://jakarta.ee/specifications/platform/8/apidocs/javax/ws/rs/core/response), we will see that it implements the AutoCloseable interface, do we need to explicitly close the responses or use try-with-resources, I have never seen anyone do this, can there be a resource leak here?

Thank's!

Hi Adam,

long time no writing from me, just too busy but always watching the sessions on YouTube after they air.
A quick question: is there an elegant way to find the name of the method one is in?
At the moment I do this
var action = (this.getClass().getSimpleName() + "." + getInstance().walk(frames -> frames.findFirst().map(StackFrame::getMethodName)).get());
but I definitely don't find it elegant and code must be performant and elegant.

Thanks again,
D.

Hello! You use the Quarkus framework a lot, it's a fast growing framework with very frequent updates. Do you often return to old projects to upgrade the version of the framework in them?

Hi Adam,

Thank you for the show!
I recently deployed a small Quarkus application to AWS Lambda as a monolith function and so far it has been working great and it's easy to maintain. Also it's nice that we can switch to Fargate easily if we ever need to. Do you have any experience on how big the monolith functions can be? Is there any limit in practise?

Hi Adam,
How could you protect your war from being decompiled ?
