[GitHub] [httpcomponents-core] horizonzy opened a new pull request #226: Add workaround of java nio bug
horizonzy opened a new pull request #226:
URL: https://github.com/apache/httpcomponents-core/pull/226
Recently, I found my web programer cpu spike. finnly I found it should be java nio bug. refer eclipse/jetty.project#2205. I notice in my project, the logic in `org.apache.http.impl.nio.reactor.AbstractIOReactor#execute`, exist ` readyCount = this.selector.select(selectTimeout);`. This is the reason of cpu spike. So I want add a way to workaround it.
I am not good at nio code, this is my clumsy code, I hope it will solve the cpu spike problem. If it can't work normally, can community create a pr to fix it? Thanks very much.
