I even tried to use a new RetryTemplate per call, but the leak is still there:

> When processing requests using the JAX RS client which used the new
> HttpClient, there is a memory leak.
> We found this when running it in spring boot using
> {code:java}
> @Async{code}
>
> I have tried to reproduce it using the attached code, and it seems to work
> with a low heap size.
>
> You can execute the code like so:
