---------------------------------------------------------
IdReadWriteLock in branch-1 only supports Long as key. Though I see in master branch, it supports generic now. But there are multiple commits touched this file need to be reviewed and back-ported if we want to use it.
May I open a new Jira issue to track this effort: "backport new IdReadWriteLock implementation from master to branch-1" and mark it as a dependency for this Jira issue.
