Description
Hi,
the reactive implementations seems to have some memory leaks.
I would guess it's either CloudEventHttpMessageWriter or CloudEventHttpMessageReader but I'm not certain.
I build an example project with a very basic setup and the latest dependencies: joke/cloud-event-leak. You can run the CloudEventLeakApplicationTests which basically fires off some requests until a buffer leak is detected in stdout.
