that's the 'concerns' I share as well: it a little burden on getting back contributions, since the source of the server is java. Also, what would happen if others decide let's add Ruby and also Perl for some sort of tests? That would mean a language nightmare, IMO :) We reject the PR.

Groovy is a much "easier" language than Java. Sure it will allow people to write some particularly hellish code, but we just punt those PRs. Punting the PR is also the answer for what happens if someone adds Ruby or Perl. > > Thank you for additional advantages, concerns or proving some of those > are not > valid. > Pros of Groovy: * Built in examples of how to call the code from a Groovy based application. * It gives us a carrot to hang in front of community members who might not want to write Java or who want to stretch their polyglot legs.
