I'd say our customers would think we're slow to support new Java versions. But I'm also pretty confident that they've never heard of Clojure and probably not even Scala. I added support for Groovy a few years ago and it's received very little attention despite the fact that it often makes it possible to apply code changes immediately and avoid the long (2-3 minute) application restart time. Our customers are mostly fortune 1000 companies, the people we deal with are not very technical and almost always outsource all of their development work overseas. They're also very good at finding outsourced developers with minimal skill sets. So a language with a smaller pool of developers would probably be seen as a negative.
