Noticing leaks in release of byte buffers about spring-cloud-gateway HOT 8 OPEN

Please try with the latest versions as there have been a number of fixes made in this area

from spring-cloud-gateway.

We tried with 4.0.9, we still see the same issue.
We will build a sample app and share it.

from spring-cloud-gateway.

The latest version is 4.1.3

from spring-cloud-gateway.

We cannot accept 4.1.3 as yet coz as per the dependency of SCG it needs Spring Boot 3.2.x and our applications are not ready with SB 3.2.x as it has many changes.
We are currently on SB 3.1.x.

Hi,
I am attaching the applications that I build to reproduce the issues.
demoMemoryLeak1 application have the webclient for sending the request running on port 8080
demo2 is the SCG application running on port 8089
stub-app2 is the stub application the on port 8087
Start all three application and send the curl request attached below
while true; do curl --http2-prior-knowledge --request GET 'http://localhost:8080/instances' --header 'x-http2-scheme: http' -H "Content-Type: application/json"; done
demoMemoryLeak1 2.zip
demo 2.zip
stub-app 2.zip

I am also attaching the results of my test run for the simulation of this issue. As per my assessment the issue is arising because the SCG is not able to handle the DATA packet which is having the length as zero. I am attaching the screenshot of tcpdump along with tcpdump file and the logs which shows that Data Leak is happening.
