@n1hility Hi Jason, I need to use JDK8's very own LongAdder (and corresponding Striped64.java) here. Google's Guave does not expose this class publicly (silly..) and even though Infinispan core has this backported too, I don't want to introduce such a dependency to mod_cluster subsystem. Is there some reasonable place to get this bacported class from or should I move it to some sort of common module (anyone else want it?) or just leave as is? Thanks! Rado
