job offers: Scala is a plus

Seen here, the CRM Company (a French company) is hiring J2EE developers.
What's different from the other job offers ? It's the first offer that explicitly mentions that knowing a JVM-based language such as Scala is a plus:
"La pratique de langages tiers ciblant la JVM est un plus (Groovy, Scala, JRuby / Ruby on Rails, Rhino)"

Hope to see that more and more (and not even within french offers :)) ...
