Groovy Programming Language gets the thumbs up
from all 16 of the voters on its JSR application.

Good luck, James. I hope you can make this work!
Job #1 has to be establishing seamless support for Groovy->Java, Java->Groovy
and Groovy->Groovy interaction.

Details of the vote can be seen here.
The only comment included with the votes was from Sun Microsystems:

Sun is happy to see Groovy proposed as a JSR.
Having additional interesting languages for
the Java platform seems like a Good Thing!
