Hi,

I don’t think anyone disagrees on the usefulness of @Contended. Beyond the JDK and 166 are there any more usages out there in the wild?

My take after browsing through some of these external libraries is that most people still use non-portable (but usually effective on common platforms) manual padding hacks. I imagine that they do this so that the code does not break on pre-jdk8. Given how this is turning out, they will have no motivation to change what they do until jdk10 or so. Sigh.
