Description

In httpCore NIO v4.4.15, we can observe a CPU spinning condition when a slow writing client sends a HTTPS GET request with a large payload. I have attached a sample HTTP server and a client to reproduce this issue.

I tried this scenario with the fix [1] as well. Still, this issue was there in java 1.8.0_312.

Could you please look into this?
