[ https://issues.apache.org/jira/browse/HTTPCORE-720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17626569#comment-17626569 ]
Oleg Kalnichevski commented on HTTPCORE-720:
--------------------------------------------
[~sanojpunchihewa] Please _DO NOT_ reopen tickets that have been resolved unless you have new findings directly related to the original issue.
If you want more frequent updates please consider upgrading to HttpCore 5.2.
The fix in question is considered minor and therefore does not warrant an immediate release.

> 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?
