I run the both blocks fine in CIDER REPL, that's weird.
I have the following special settings for ob-clojure.
```elisp
(add-to-list 'org-babel-default-header-args:clojure
             '(:eval . "yes"))
(add-to-list 'org-babel-default-header-args:clojure
             '(:results . "value pp"))
(add-to-list 'org-babel-default-header-args:clojure ; for Clojure `dotimes'
etc.
             '(:show-process . "no"))
(add-to-list 'org-babel-default-header-args:clojure
             '(:noweb . "yes"))
```
