JRuby exists ...

http://jruby.sourceforge.net/

but it's under the GPL (not even under the LGPL).

Blech.

I realise that this person may be perfectly legitimate to do this 
(although I'm not super sure; it's likely based on the existing 
source and claims to be 1.6.7 compatible for most purposes), but it's 
still nasty, IMO, not to do it under the same licence as the base 
implementation.
