Does not Work With Java 7 #12

Closed jeffdc closed 11 years ago

jeffdc commented 12 years ago

On Java 7 (Linux 64bit 1.7.0_06-b24) all of the unit tests fail with a NullPointerException. If I switch to Java 1.6 all is well. I spent a bit of time trying to chase this, but I do not have a reliable Groovy dev environment set up and was spending all of my time Yak Shaving.

Here is the stack trace:

Strong, could you take a look at this? I don't know the Spock stuff

it seems JDK dependent, this only occurs on openjdk

patch applied, thanks
