What version of the product are you using? On what operating system?

noop version: 0.1.0

Running: java -version 

Yields:

   java version "1.5.0_20"
   Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_20-b02-315)
   Java HotSpot(TM) Client VM (build 1.5.0_20-141, mixed mode, sharing)

OS: Mac OS 10.5.8

Please provide any additional information below.

noop looks very clean.  I'm looking forward to using it.  

I'm guessing that the Scala class files shipped with noop were compiled under a 
previous version of Java and that I need to install that version 
of Java to get everything working.  Or can I install a version of Scala that's 
built for my current version of Java?

Thanks!!

The continuous build is compiling with Java 6, so you need to run with a Java 6 
VM.

You could also compile from source with Java 5. I haven't tried it myself, it 
might currently work, but no 
promises that we won't introduce a change which uses Java 6 apis. I think we'll 
officially target Java 6.
