I just upgraded to JetGroovy 1.0.13420 and Selena #7613, and I can no longer run or debug an existing Grails project. I believe that the problem is caused by something in the launcher because copying and pasting the same command line to a shell in my project directory starts the project with no issues. It appears that it's double-prefixing my home directory in the missing files path ("/Users/mkw:/Users/mkw..." instead of "/Users/mkw..."). I've cleared out all my caches and even tried creating a new run configuration in order to fix this, but no luck. If any project or config files would be useful in tracking this down, please let me know. The full text of the console when trying to debug is attached.
