:column metadata for sets should be an int

     meta
     (map #(vector (key %) (val %) (type (val %)))))

([:end-column 11 java.lang.Integer]
 [:end-line 1 java.lang.Integer]
 [:column 1 java.lang.Long]
 [:line 1 java.lang.Integer])

Trying to eval the result of the above causes the compiler to throw: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer. This only affects Clojure 1.5.0 and Clojure 1.5.1.

The attached patch, 0001-TRDR-22-column-metadata-for-sets-should-be-an-int.patch, adds a call to int in read-set to ensure that the :column metadata is an int.
