The above code snippet is sufficient to reproduce the behavior. Groovy compiler does effectively the same while discovering classes. See the following link and the stack trace below. https://github.com/apache/groovy/blob/2c73607831676d9f9e1bc988f4acdab1ae4eaffa/src/main/java/org/codehaus/groovy/vmplugin/v9/ClassFinder.java#L177 If you still need a project to reproduce, let me know.
