Its an optimal choice for business. Banks, financial institutes, pharm companies and other boring places already has a plethora of experienced and moderately motivated java developers.

It's hard to sell them new features/projects when their devs cannot decypher the language you used. (Eg. scala) You can't really put a finger on what you gain from using a new language apart from it's harder to find someone to work with it an he will ask for more money.
