Default interactive console in Play 1.2

[Travell]

I'm trying to get the default interactive console working in Play.
I'm working off of the docs found here:

https://github.com/playframework/play/blob/master/modules/console/documentation/home.textile

This is where things fail:

Compilation error (In {module:console}/app/utils/
InterpreterHelper.java around line 9)
The file {module:console}/app/utils/InterpreterHelper.java could not
be compiled. Error raised is : The constructor JPQL() is not visible

play.exceptions.CompilationException: The constructor JPQL() is not
visible
