Given is the following java project with Xtend and Java files: test.zip.

An Exception is thrown when performing a Rename Refactoring (Alt+Shift+R) on the variable ARROWHEAD__E.

Start with LocalClassAwareTypeNames.java, where the stack trace reports the NoSuchElementException, then trace how RenameRefactoringController.java reaches it through reference finding. Reproduce Alt+Shift+R on ARROWHEAD__E in the attached project and confirm the refactoring completes without throwing the exception.
