RefactoringFactory.collectRefactorings() seems to call SGLRParseController.getEditor(). The editor is only assigned to it after the editor has parsed for the first time, so it shouldn’t be accessed on service initialization time. In my case, it returned null, breaking the refactoring service.

Could not load refactorings
