I can reproduce this on Groovy 1.5.4, but not 1.5.5 or 1.5.6.

Would it be possible that Eclipse is somehow using Groovy 1.5.4?

I am trying to get details of the change from the Groovy devs for more information. In the meantime, can you please verify that you are indeed running with >= 1.5.5.

This is definitely related to the change in r158

This appears to be the symptom of Gldapo now requiring Groovy 1.5.5 or greater. I have created a separate issue to update the documentation to reflect this.
