True, I played with Rhino, Jack / JSGI early on, and did a couple projects with Aptana Jaxer around 2009. It was not really an option most developers would even consider, though.
Node came out in 2009, and writing server-side JS was still a fringe practice for a couple more years, so 2010 is me being generous to avoid comments on the exact timeline ;) It really picked up mainstream adoption around 2011-2012.
Was Rhino ever anything other than a minefield that you were essentially pigeonholed into using for compatibility reasons or something similar? I have used it before but only because we had specific technical requirements that demanded we run Javascript on a server-side JVM implementation.
