    Description

      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

      @Async

       

      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:

      mvn compile exec:exec
