Description

I just saw this thread on the cascalog list: https://groups.google.com/forum/#!topic/cascalog-user/Pe5QIpmU0vA

Apparently the "WARNING: some? already refers to: #'clojure.core/some? in namespace: jackknife.seq, being replaced by: #'jackknife.seq/some?" results in a NullPointerException when trying to AOT a namespace that results in the message being output.

Reproducer:

1) lein new aotFail
2) Edit project.clj
;add as appropriate
:aot :all
:dependencies [[org.clojure/clojure "1.6.0"]
[cascalog "2.0.0"]]
2) Add "(:use cascalog.api)" to the ns block of src/aotFail/core.clj
3) lein compile

Output:

Compiling aotFail.core
WARNING: some? already refers to: #'clojure.core/some? in namespace: jackknife.seq, being replaced by: #'jackknife.seq/some?
