Facing high CPU by one of the default I/O thread In Wildfly 10.1.0 Final. Looks none of our application component thread is consuming.

Can somebody check what is triggering this issue? I attached the thread stack to this Jira. This is blocking our releases. When the CPU cores are high in number, multiple default I/O threads will kick in consuming the CPU in 90~100% range continuously.
