Reflection warnings, such as for reflective method calls, are printed with the full source path (Compiler/SOURCE_PATH). This is different in case of the warning about loop recur args, printed with the source filename only (Compiler/SOURCE):
(set! *warn-on-reflection* true)
(defn reflective-method-call [] (.substring (try "") 0))
(defn boxed-recur-arg [] (loop [i 0] (recur (try i))))
...which prints:
Reflection warning, /home/pawel/dev/project/src/core.clj:22:33 - call to method substring can't be resolved (target class is unknown).
core.clj:24 recur arg for primitive local: i is not matching primitive, had: Object, needed: long
Auto-boxing loop arg: i
IMHO, the path is useful, especially if the filename is generic and inside a dependency.
