Funky build issues

Hi,

I'm using version #0.1.12084 and I'm having weird build issues. I have the following simple Groovy class:

class Person {
def firstName
def lastName
}

then inside a Groovy script I do this:

def p = new Person();
p.firstName = 'scott';
p.lastName = 'walter';

println p.firstName;
println p.lastName;

however both my println's are returning null when I run the script. However if I go and delete the generated class files in out/production directory and then run the script I no longer get null. But if I run the script a second time (without changing any code or anything) I get null again.

Any ideas what is going on here?

Scott.
