Hard to call this a Java bug when many other, non-Java things are affected. It's a critical Linux bug that causes futex to timeout, and anything that uses it to behave incorrectly.

- tommi 14y agoecopoesis, you are not the only one saying that it's a linux bug instead of a java bug even though the link title says "Critical Linux bug that leads 100% CPU (leap second)". Did the link title change from a Java title, like the article, to a Linux title to match the actual root cause?
