Pulled this from clojure assembla ticket #436 to clojure-contrib
See clojure-436

What (small set of) steps will reproduce the problem?
$ java -cp lib/clojure-1.2.0.jar:lib/clojure-contrib-1.2.0.jar clojure.main
Clojure 1.2.0
user=> (require 'clojure.contrib.json)
nil
user=> (clojure.contrib.json/read-json "")
java.lang.IllegalArgumentException: Value out of range for char: -1 (NO_SOURCE_FILE:0)
user=>

What is the expected output? What do you see instead?

Expected:

(if eof-error?
  (throw (EOFException. "JSON error (end-of-file)"))
  eof-value)

What version are you using?
1.2

Was this discussed on the group? If so, please provide a link to the discussion
[13:51] <_na_ka_na_> Hey guys I think there's a bug in clojure.contrib.json at line 116
[13:51] <_na_ka_na_> in clojure 1.2
[13:52] <_na_ka_na_> it has a (char i) and then checks for (= i -1) ... but (char -1) fails
[13:52] <_na_ka_na_> where can I report it ?
