Hi,
This becomes problematic as the containing class is part of a much larger system. I am building a a Groovy Parallel Patterns Library and this is just one of the demos of the library I am working on. I have had the code working in an Eclipse envrionment with an earlier release of 2.4 probably around 10 or 11. I have now moved to Intellij and this has thrown up the problem. I will download a previous release of 2.4.n and see if I can get the code to work and that may then help you to identify the problem. I have been doing a major revision of my codebase moving from Eclipse/Mercurial/ Bitbucket to Intellij/Github and this has thrown up this problem.

Perhaps we need a bigger sample to track down your issue. Cheers, Paul.

I have converted to groovy2.4.15 and the same error occurs. I am running under Intellij IDE and had downloaded the sdk bundle.
