The Clojure run time throws IllegalArgumentException in a lot of
different places. It does also throw RuntimeException
in several places. It traps exceptions generically (catch (Exception e),
catch (Throwable t) ) and may have thrown a RuntimeException back
to upper layers instead of the original\ IllegalArgumentException.
Did you print the RuntimeException ? There might a be a text messages
there that can tell us where it came from within the Clojure run time.
